A little background -at one point I had 4 cats, not because I set out to, it just...happened. I've lost 3 out of the 4. The last two going just a couple months ago.
We got one rescue cat and it took a little while for him to adjust but he's a total love now. I was on the fence about getting another. I feel badly for the new one as he's only 2 and playful and my 10 year old overweight cat isnt.
I had another cat come for a trial run. He was very shy but had started to come around BUT, he liked to nip when you'd pet him. I mean he'd bite, and not always gently. Never broke the skin or anything but it did hurt. My son (14) wouldn't touch him at all for fear of being bit. My daughter (16) would only pet him with a sweatshirt sleeve pulled down over her hand.
I had the lady take him back, but I'm wracked with guilt. I dont' know why really. It's a no-kill rescue. We only had him 2 weeks. I guess it's partly because the young cat did seem to enjoy his company. And I just feel so badly for the rescue that went back. He was a nice cat, just wouldn't stop biting (and the foster woman said he still did it to her, so it wasn't like he was going to grow out of it after 2 years).
Anyhow, this is probably the longest post I've ever had on here and it's about CATS.
