My 4 year old cat has been in and out of the vet for the past few months. It all started with allergies where she was losing her hair and getting all scabbed up. Then, we found she had tape worm and I had no idea how she possibly got that...she is on advantix and never goes outside. Now, she is biting at her leg all the time and has caused it to look all red and nasty. For the past month she has been going to the bathroom on my bed. That stopped when I started closig my door all the time. Now, she has moved on to the loveseat and couch. I scoop her litter box two times a day although it is out on the patio and she does share it with my other cat who has been around for about two years. SHe never had a problem with this before. My husband wants to get rid of her, but I am one to believe when you get an animal you make a life-term commitment to them.
