A true sign that Cat Clinic was the right choice for us is that, while en rte, our cat whined all the way there. But as soon as we pulled into the parking lot, she was silent. Once inside, she was meowllow, calm, and met no strangers. Her perspective matters. The Dr., the staff, and fellow patients were all friendly, compassionate, and professional. It's been an overall great experience. Our kitty is healthy and happy. I highly recommend Cat Clinic. ​ read more

This place scared me when I first went in. I'm not used to dealing with various, outright, let's just say Dr. Oz would not recommend this place. Thankfully they turned me away immediately the second they saw me. I thought they were real veterinarians there. They didn't treat me of my pet as such. Thank god for Pasadena Humane Society read more

Shortly after noticing my cat had an infected tooth, I called a few vets in my area. This was the ONLY place that would give me a quote of how much the procedure was likely to cost me. I found it to be such an honest approach and I chose to make an appt. When I walked in the staff was very friendly. Dr. Loo was also very friendly, caring, and patient when handling my cat (He was very afraid and had peed in his carrier). She cleaned him up a bit and then examined him. I was told the tooth was indeed infected and would need to be extracted. They were able to do the procedure the same day and I was able to pick him up a few hours later. This is the first time I've owned a pet and the first time I've seen him sick. Seeing him in pain was just heartbreaking for me. It made me feel so much better to know that I was leaving him in the hands of caring and patient staff. I picked my cat up near closing time and they were very patient with me and the dozens of follow up questions I asked regarding his aftercare (I was a VERY worried cat mom ). Also! My total ended up being less than what they originally quoted me on the phone! Overall, they provided amazing customer service and care for my cat. read more

I highly recommend this clinic, the whole staff is very attentive and the doctor is very experienced, my cats felt loved here Also very affordable with payments plans read more

I just learned today Dr. Diegmann of the Cat Clinic in Pasadena CA passed away in February 2023. He was a caring, loving man who saw the best interest of his patients and those who love them. He is and will be forever missed. I first started taking my feline friends to the Cat Clinic in the 70's, and continue to do so. The staff is professional and caring beyond reproach. Reggie at the front desk is a star. The Clinic goes on under the guidance of Dr. Lu, Dr. Diegmann's wife. So for myself and my wonderful cats past and present: Enkidu, Obi, Cat, Kitty, and Biscuit a shout out to the best DVM I have ever had the privilege of knowing. R.I.P. Dr. Diegmann. There is no doubt you are surrounded by your loving felines in a place called Heaven. read more

The Cat Clinic has been our "go to" veterinarians since we moved to Pasadena years ago in 1979. They have taken care, and are taking care of now, of the several cats which we have had since then. The staff are all very attentive and courteous, and the doctors are equally attentive to the cats' needs. I recommend this facility without any reservations whatsoever. read more

Cat Clinic - Zerlina (L) and Cooper (R) pondering their next move. - Veterinarians Near Me - Pasadena, California

I get it, the place is old. The doctor is older. Maybe they will still break my heart but if you are lucky enough to become their patient - they take such good care of your cats. Also I'm not about to spend $$$ on specialists right now for my cats during a pandemic where a normal vet appointment can take hours if at all. Cat Clinic just delivers! Holiday and night phone calls, easy walkins, and old school reasonable care and advice that doesn't involve me going somewhere else before their doctor can see me. They get the job done there! I adopted a kitten and she sneezed blood for a month. I was able to walk in and they recommended and performed major surgery and now she is all better! My vet friend said they charged half of what her clinic would've charged, and for that I'm so grateful. I wish Cat Clinic and the doctors and receptionists all the best for all they have done for me! I think the trick/major problem is getting an in/first appointment- and also be very specific telling what you are worried about if you do get that appointment. This is no time to be precious about feeling offended! Get your in so you can get the easy, good care. read more

This continues to be a wonderful and caring place now when my old cat Rosie was diagnosed with kidney cancer. Dr Lou (spelling?) and all her staff were very gracious when it was time to say farewell to Rosie. The staff all gave Rosie the best care but she had become old. A sympathy card was sent now after a week which I appreciate very much. I recommend this vet because they know cats and have very nice staff. read more

Things seemed to have changed since the elderly Dr D passed away. Although the reception has always had peeling paint and has a strong smell of urine. The one receptionist is quite arrogant and condescending. We've spent thousands there for one of our cats. They are not shy charging not hundreds, but thousands of dollars for various procedures. We are of the opinion that in shaving an area of our cat's fur, they cut into his skin and caused a wound. They wanted to charge us to treat it! We won't be back. read more

I was devastated to learn of Dr. Diegmann's passing. He was only a month older than I! He and his wife, Dr. Beverly Loo, cared for our cats for the 15 years we lived in Altadena. In 1998 we moved out of state. The care that Dr. D. gave our cats was unsurpassed. When our beloved cat Tommy was terminal, Dr. D. walked my retired husband through the last stages, and a compassionate euthanasia, while I was working. My husband passed in January, 2023, a month before Dr. D. RIP to a kind man, a fine veterinarian, and a tireless worker. Yes, he was at the clinic at night! Condolences to Dr. Beverly Loo, his beloved wife and partner. read more

The doctor was usually nice BUT his old , wicked witches that worked in the front office ( not sure if they're still there) less than caring and always mean. They are rude and make you feel unwelcome and overall just treat you like crap. I don't know why they were always so bitter and mean to everyone one. Why would the doctor put up with this? You're only as good as your staff. My beloved cat has passed now, but for anyone else out there don't put up with bad treatment, go Somewhere where you're treated properly. You've got enough on your plate with a pet that's not feeling well. There are lots of nice clinics out there. read more

Have had several cats and been to various vets. Vets are very special people who can do this so I give a lot of leeway to a profession that needs more. I have settled on the Cat CLinic. They were able to see my kitten when I found a lump. I had no idea it's sister had bitten her and turned into an abscess. The bite was not visible under her fur andhad not bled. It became infected and Dr. D treated her very quickly. Yes he might be a very old school vet but the clinic has been very receptive, available and caring. I no longer beg our old vet to see us as it would take months. The more modern that clinic became, the more expensive just for a simple check like this abcess. I am sticking with the cat clinic. It's great to have a vet that sees only cats as one of mine has anxiety. After sitting in a waiting room with dogs would freak him out for days. Appreciate finding the CAT CLINIC and it's vintagy atmosphere. No frills just one on one attention read more

I really like this place! I called on Sunday, and they fit me in Tuesday afternoon. More impressive, I was 15 minutes late and they still helped my kitty with a warm welcome. Stray cat, first time in a carrier and they were great with her. read more

This vet and staff are very friendly. They treated my cat with great kindness and patience. She actually liked them and was a model citizen, no fuss during the appointment. read more

Cat clinic and the people at work here are amazing kind and knowledgeable the work they do is definitely necessary in this review is Neely to respond to that idiot Rocky that left 1*13 days ago pet overpopulation it's not a mess and you are the ignorant person that overpopulation is an epidemic proportions have you ever went to or worked at an animal shelter and saw how many cats and dogs and they euthanize every single day and just one shelter you would probably change your mind you sir aren't idiot and shit it on any pencil really god you have no children read more

Dr. Diegman and his staff are extremely compassionate and caring people. Dr. Diegman may be on the older side, but he is very experienced with the well being of cats. He took care of our last 2 cats, even put one down for us. After 5 years of not being back, he still remembered both of them. We now have a new kitten, not living in the area anymore, we still want to come back and have him as our vet. I highly recommend, no complaints here! read more

It's been a while since I've taken a cat to CatClinic as it's a haul from downtown LA, but the drive is worth it, if you have the time and your cat doesn't mind. t's one of the few places where I know the vet, Dr D., can recognize symptoms and behavior that would be missed by other vets. As he stated: "I wasn't the best in vet school, but when all you do is cats, for as long as I have, you learn a thing or two about cats that others won't know." ..or words to that effect.. And my cats like the fact that there aren't dogs or other varmints around to upset them. Sometimes a bit pricey so keep track of what you're spending. As far as the bad reviewers concerning reception staff, maybe they were asking for it. You know the type. Do it for your cat. read more

These folks are very knowledgeable, calm and accommodating. I'd highly recommend them!

Reggie was incredibly rude when I called to to simply inquire about the business and if they were taking new patients. I'm not disappointed by the lack of appointments available but at the level of rudeness and unprofessionalism from the person who is essentially the voice of the office. Very disappointing. read more

Just moved to Pasadena and was looking for a place to take our cat. The staff was rude, our cat was treated poorly. They never followed up with the tests results we had done. We tried to call several times but they also never answer their phone. Finally got ahold of them with minimal insight or further assistance. Their facility is outdated and they used outdated methods. If you're looking for a new spot keep looking. read more

My experience with the Cat Clinic began 20 yrs ago, had just moved to Wilmington and my beloved cat Munch got sick, don't remember how I stumbled onto the C. C. Their certainly many places a lot closer. I left a message with the answering service and a few hours later Dr. Diegman called, I was amazed how genuinely kind and caring person he is. He has definitely saved a couple of my cats. Euthanized my cats that were terminal and even let me slide for at least $1,000. with my cat Whodini. Call me a sentimental old fool but the sympathy card I got from Diegman a couple weeks later of a cat sittin on a cloud definitely brought tears to my eyes. I feel really bad for all the people that have had less than a spectacular experience. I think he is a great veterinarian and a wonderful, caring person. read more

The place smells terrible. A stench of urine and wet cat food is the best way to describe the smell. They have no central air so when I went there on a very hot day the stench was extremely unbearable . I waited outside while they treated my cat. I was suppose to go for a follow up but didn't. I couldn't deal with the smell. No place of business should smell like this. I have been to different veterinary clinics over the years and have never encountered anything like this. read more

Took my cat here for a number of issues he was experiencing and we got the most thorough, thoughtful diagnosis we've ever received. Dr. Diegmann is a wizard with cats. It's not the most high tech, glamorous vet office, but that's not what matters. I don't care if the vet uses a handwritten chart if my cat gets the care he needs. I also felt comforted by all of the little knickknacks and cat photos/decorations in the lobby. For those that complained about the smell, please find me another CAT ONLY clinic that doesn't smell like cats. Within the same 4 days, Dr. Diegmann saw my cat for an initial visit, analyzed his lab work, and performed surgery and x-rays. He took the time to explain everything to me and answered all of my questions. I think it's unfair that people have left one star reviews because they didn't like what happened on one phone call to the clinic. For what it's worth, Reggie at the front desk has always been lovely to me. I will also say that while my initial visit was on the more expensive side, the surgery and x-rays were much cheaper than I've paid at other vets. This place should be judged by the care and attention they provide to your cat, and for that (and more) I give them 5 stars. read more

This place has to be the worst clinic u can take your cat too. This place said my cat was hiv positive when he isn't, tried scamming hundreds of dollars out of me. Place is a hole in the wall ready to be shut down. read more

This was the only place I could walk into and be seen the same day. I brought a small kitten I found and they have provided excellent care. This was my third visit, the kitten is happy and healthy! We'll be back in a few weeks for neutering. read more

Wow I was so astounded by the rudeness of the lady who I spoke with on the phone. My precious little kitten has been throwing up and I'm looking for a vet in the area who specializes in cats. I called this morning and asked if they were accepting new clients (because they had relatively good reviews on Google) and was told to call back in 40 minutes. I did, and was asked to explain in detail why I'm looking for a vet and details about what's going on (all standard assuming they ARE taking new clients) then I'm put on hold for a few minutes and then the lady came back and told me they're not. Ok bummer. So I ask if the lady can recommend someone in the area for overflow patients since in most industries that's common practice. She said something to the effect of "we don't do that" and then when I said I'd really appreciate if she could, she goes "WHAT. YOU DONT HAVE INTERNET!?". I guess it's a blessing in disguise that they didn't accept us because I never want to meet that lady in person. Just so unkind. Unnecessarily unkind. read more

They killed my cat years ago. He was perfectly fine just took him in to get his yearly shots... No one should take their cats here. Not only did they chop his nails till he bled, they also cut off his whiskers... Seriously WTF? That just goes to show the lack of care and treatment of pet. They ended up giving him the shot wrong which lead to him having a stroke but it also didn't help that it seemed like he was tortured before hand. No one can describe the pain and regret I have of taking him there. I thought that since it specialized in cats that they knew what they were doing. I was wrong but I hope not to have anyone else experience what I went through. read more

Be very careful when using this clinic. I originally took my cat here when he had been attacked by another animal. He was well cared for and I am sure they saved his life. However I begin using this clinic for his regular care and boarded him when I went out of town. On more than one occasion I returned from a trip early, and when I asked if I could pick him up early I was told "no." I once went in unannounced and asked for him, and he had been sedated. Not cool. They also used to charge me for a lot of unnecessary "procedures" such as draining his anal glands . . . Good in an emergency situation, but don't use this place as regular care for your pet. read more

I don't know where all the rude reviews are coming from on this vet. I've been a customer for 30 years plus and have never had the kind of experience others are complaining about here. The staff are all long time employees with whom I've never had a complaint about. Yes, it's expensive, but that's because the vets pay a living wage to their employees. Whenever one of my cats dies, I always get a condolence card from Dr. Diegmann. What more people want from a vet, I really do not know. read more

Dr Frank Diegmann DVM treated my cat well. He listened to me, and agreed to go with the less aggressive treatment that I chose. When my kitty had an emergency, I called in the early hours to listen to their message and find out which emergency hospital they refer to, but Dr. Diegmann had a message service who contacted him, and he actually came on the line and gave me a same day appointment on a day they are closed. He treated my cat and kept him for several days. Now my cat is perfectly fine. Dr. D worked out a way to manage the expense with me that is very kind and uncommon. He really listens when I explain why I make the choices I do such as not vaccinating an indoor cat. The only caveat that I have is that my cat hates the place. It was the first veterinarian in ten years who had to sedate him in order to take a blood and urine sample. After my cat had to stay for several days, he was extremely distraught and behaving with great distress. He was upset to an unusual extent, showing behavior I had never seen, growling when I came close, walking around the house howling although he is normally silent and purring. He returned to normal after three weeks. I would never go there again. My cat is very stoic. Only extreme mistreatment could cause him to howl as I described. I would never take another cat here. My poor cat absolutely freaked out. He was an even tempered calm kitty. They encouraged keeping him for days instead of teaching me how to give him his treatment. When my folks went to visit my kitty, they brought him out bound in a towel and complained about how nasty he was. He was never difficult before this place, but after he went here he could not tolerate any veterinarians. He was profoundly traumatized. I don't want to know what happened to him here. It makes me feel horrible to think what would traumatize him so horribly. I feel creeped out every time I drive by. read more

Terrible experience. For 1, the clinic stinks like cat pee... I should have ran away just because of that. The vet needs to retire. He didn't listen to what I told him, then he took my cat into a separate room to examine him... Charged me a ton of money for things I didn't witness him doing. TOTAL BS Then when I asked for my cat back because I was nervous about what they were doing to him behind closed doors, they walked out with a kitten and handed it to me thinking it was funny. NOT FUNNY. Don't go here... There are plenty of good vets in the area & this isn't one of them! read more

Came in to ask about Cat services for my 9 year old Persian, was promptly greeted with a "what do you want". No welcome, no hello. Maybe it was an off day for the staff but very unwelcoming, if this is how they treat me I worry about how they would treat my animal. Friendliness builds business and connections. Quite disappointed with the attitude of this establishment. read more

Found this vet after a recommendation from a friend many years ago when my brother's cat had urine crystals. Our regular vet had refused to see the poor guy on a Saturday after 20 years of patronage. Well Dr. D fixed him right up and he never had another problem with his junk and lived out a long happy life along with our other cat who became a patient here as well. Now that I run my own household I decided to bring my own babies here. Nothing is more serious to me than my cats and I would not trust them in anyone else's hands. read more

I was in the Cat Clinic on May 7, 2019 and Dr. D and his staff are wonderful. So helpful and friendly.

Today at 3:30pm I called to see about getting an appointment because my cat hasn't been eating and just hasn't been herself since we moved. The woman who answered the phone was so rude. I cannot believe how nasty her tone was. She was harsh for absolutely no reason, told me they weren't accepting new patients and then abruptly hung up the phone. I cannot believe how rude she was. It's bad enough I'm worried about my cat but to be treated that way is terrible. read more

I called to see if my cat could come in because she has an upper respiratory infection. They informed me that they aren't taking new customers and hung up. Nice customer service skills! If that's any indication of how this place works then glad they turned me away! read more

I just came back from the office and I was very surprise by the old fashion way of vets! Taking an appointment with them was first so much easier than waiting for hours in your car!!! And I just trust them! My cat was very injured and after an X-ray, I knew that she will survive! They were very supportive and professional! Yes, it's smell a little in the office! But it's all about cats... read more
