Amitriptyline for Spraying??

Sirrahved, Devon (my DIL) has really been through the ringer with this problem. Yes, Pickles is neutered, (as a kitten - is now a year old ) he has been to the vet and has no medical problems, the litterbox is meticulously clean - he started this several months ago and is literally destroying their apartment. Feliway has not worked. She has bought the black light and bacterial cleansers and seeks out every single drop she can find - is doing a pretty good job but this is SPRAYING rather than puddles so it is even harder. I think she has read everything on the Internet about behavior, spraying, etc. and is ready to tear her hair out and I feel so bad for her!! I think she is going to call the vet in the morning and ask about amitriptyline. I know they cannot afford Prozac. (Ami is about .05 a day and Prozac is about $1 a day)
Has anyone had success with Ami??? Sorry about cross posting but I am as frustrated as she is and just trying to help her - I live in another state and feel helpless:confused:

Yes, I have used it for behavior modification. It does work, I had to keep kitty in a small room with one litter box and water and food for about a week if I remember right and then clean the spots, checking with a black light to make sure they were gone and then treated with fel a way. It did the trick. But I forgot how long I kept him on it. Do remember had to ween off slowly. Good luck let me know how it goes.
