Thanks so much for the advice,
I haven't had any changes in the household. Shes had been doing this since I got her, she has even urinated on my bed in front of me once. I give her plenty of attention daily. I brush her, talk to and play with her. She greets me when I come home and follows me around the house. Sierra is not a lap cat however she loves to be around me and talks to me quite often. The only thing that she doesn't not like is when my son (that is 18) has friends over, Sierra runs in my room and doesn't come out. My son takes good care of her as well and loves her too. Sierra loves him to, talks to him and he plays with him too.
I have had to clean the couch, faux fur rug and bed almost daily. I have spent a lot of money on odor removers that work pretty good. I also use an water and vinegar solution and Baking soda for the bacteria growth. I have a spray to detour her from the couch. Just when I thought I remedied the problem I sit down to find a wet spot again. I never yell at her because I know she is doing what comes natural to her for some reason.
The women who had her before me worked at a vet. For some reason that women moved out of state and abandon Sierra and another cat. The neighbor took them in, but already had to many cats, so put them on criagslist to be adopted. They thought that Sierra needed to be the only cat because she always hide in the bedroom. Now see why I can't let go of her. I feel sorry for what she has been though. I have dealt with her problem for 8 months so it's not like I haven't tried everything I could. I guess I can try the medication you have suggested.
She doesn't have any medical problems. My vet thought that it's a behavioral problem she as probably had a long time. I am going to try the physic. I have a wonderful lady I have seen many times over the last 15 years, that is very good. Maybe she can read Sierra.
Thanks for the understanding, my friends an family think I am crazy to keep her when she has ruined so much of the furniture. (Couch and new mattress that my boyfriend let me borrow until I can afford my own) (Long Story). He is the least understand since these things belong to him!
Sincerely, LoveMySierra
