I just recently adopted a 4month old kitten from the spca. When I brought her home she smelled terrible, the whole shelter smelled disgusting and she was kept in a small room with all the other kittens and young cats. She wasn't using her litter box here at all so I switched litter and put her in the bathroom at night where the box is and finally woke up to see she pooped in it. I gave her a bath and thought we were making progress. But she sometimes hides under the couch and when she came out last night she reeked of cat urine. I didn't think cats would hang out where they pee! Could she just have terrible habits and bad hygiene from living in that nasty shelter for most of her life? Could she be ill or stressed? And how can I keep her out from under my couch? How can I encourage her to use the litter box only? Just to clarify, I switched to a litter similar to what the shelter uses, the box is very large compared to her and does not have a cover, she is going to the vet tonight. If this is going to be a long term problem I may not be able to keep her.
