Welcome to PT!!! I currently have 6 cats and I can't have any more because I feel that this is almost too much for me to handle and that I'm already over my limit. I only live in a 2 bedroom/2bathroom condo so there's no more room here any way.

If you feel you can handle another cat financially and that the cat would fit in well with your other cats then I say go for it. I'd love to see some pictures of your cats. I hope that there's nothing seriously wrong with your 7 year old cat.
