My 2 1/2 year old Persian has never squatted down in the box low enough to prevent her urine from going outside. My husband kept getting higher and higher sided boxes until she developed an aversion to the box. We discovered that she was using the guest beds sometimes and then realized she was also using the leather furniture in the den. For the past six months we have tried all sorts of things, ruled out UTIs, etc. We have finally gone to a very large box with clumping litter (we had non-clumping before), puppy pads underneath to catch what doesn't land in the box, and she seems much happier. However, she has always been very skittish since we got her at 12 weeks, and she is still urinating some on the furniture in the den. She does use her litter box most of the time but there are too many accidents for me to feel comfortable. I should also say that we are starting to do some redecorating and we have a new rug in the den that she is unsure about. I think that started this last round of peeing on the furniture. She peed on the recliner last Friday and soimetime between then and now on the sofa. I found a spot under the sofa this afternoon. The vet prescribed Prozac, but I am trying to avoid it if possible. I thought I would try Feliway as a last resort before Prozac. I have ordered the spray to spray on the furniture and the diffuser. What has been the experience of the users on this forum with Feliway?
