litter box problems
I have two cats, a 5 year old, and a 7 year old. I recently moved the furniture in my bedroom because I could smell some type of cat mess and couldn't find it in the open. I was horrified to find my oldest cat had been going to the bathroom under my bed in the same spot for what appeared to be quite a while. I know that animals may 'mark their territory' or do this if they are upset (messy litter box, jealous, etc.), however this is not the first time I've had this problem with the older cat. I got her when she was a little over two years old, where she had been rescued from an abusive and neglectful home. She is afraid to leave me room or bed if there are people over, or if there are any noises or objects she doesn't recognize. Therefor, she will go where ever she is. I have been very helpful with having a 'special needs' cat, but I'm at a loss. I really don't know what to do to help her. She does use the litter box sometimes, but this is becoming more frequent and a bigger problem as days go by (nobody likes coming home to that mess!). Ive heard about spraying the cat with water when she does these things but with her constantly hiding I have never caught her in the act, and I'm afraid of disciplining her because of her past of abuse. I'm just wondering if this is something I should consider taking her into a Vet for or if it is common in older/traumatized cats. I really don't know what to do, she is my baby and the only options people have given me is euthanasia (mostly suggested because of her age and combination of other health problems ie. bad vision, small tumors, etc.) but that is definitely the last thing i want to do to her. I would like for her to live a long and happy life without having to clean up after her constantly. Any suggestions, tips, anything???
