My vet prescribed amitriptylene for my kitty who has psychogenic alopoecia and it calmed her. Most important, her hair grew back. As soon as the prescription was completed, my kitty started chewing her hair out again. I called the Vet, the won't renew the prescription until I bring the cat back and undergo a barrage of tests which, amounts to a $400 vet visit. I'm a senior on Medicare. I can't afford that. I was hoping to purchase the product directly from you but, found that I could not do so. Amitriptylene works and I'm glad for the other reviewers who have experienced betterment in their animals.

Works wonders for our dogs.
Our girls used to get into fights and become aggressive towards each other. With the Amitriptyline they are calmer and for over a year we have had no fights. We have two Old English Sheepdogs and when they get into it, it is not pretty. Glad we were able to find something to help with them getting along all the time.

Hasn't worked for us yet
I had such high hopes for this medication, but after 4 weeks on it (10 mg a day) my 5-year old neutered male Sammie is still spraying and going outside the box. We got him as a rescue about 2 months ago and he started spraying a few days after coming here. Had been told the reason he'd been given up was for spraying but the rescue place said they'd never seen him spray so I thought I'd take a chance on him. We have another cat (they get along OK but do have the ocassional altercation) and a dog who ignores him. Sammie was found to have some crystals in his urine, so he's been on Prescription Diet c/d. Was tested last week and still has a few crystals; was put on an antibiotic because they found a few red & white blood cells in his urine, too. The antibiotic gave him diarrhea, but thank goodness he at least does #2 in the litter boxes. The vet says she wants to clear up his urine before trying another medication, which I guess I can understand, but cleaning up after him every day is no fun. I can easily see why spraying is the #1 reason for turning in a beloved kitty cat, but I haven't given up on this guy yet. The vet suggested I get a leash and harness for him and get him outside, as that might help. I'll try anything at this point. There's also a new Prescription Diet food for "urinary stress" which I'll try. One of the vet techs says it helped her mother's spraying cat enormously.

kitty uses litter box again
Honeycat was semi-feral when I adopted her, and she's always been nervous. I've had her 10 months and suddenly she started going outside the litter box. I suspected it was her nerves, and a urinary test cleared her of medical issues, so the vet prescribed amitriptyline to settle her down and make her feel more secure so she doesn't need to "mark" territory. The one drawback is that it's hard to get her to take the pills, especially half-pills, because they are so bitter.

PetMeds Came Through
My cat started marking furniture (he's 7 and was neutered as a kitten#. After a series of test my local vet felt it was all anxiety disorder #my other cat was determined to have total control). She put LE on Amitriptyline & it worked! However, I was buying from my vet as a much higher price. Since I have 2 cats, 2 dogs & a horse to take care of, I welcome any discount I can get! I've dealt with PetMeds for years so new to go to their site. Highly recommend them.
