We had a similar situation. We had a dog door and a new kitty just let herself inside for our can’t food.
She actually got to the point where she’d come in my room for cuddles and a nap in the middle of the night.
But something wasn’t right. Her coat was a little too nice.
So I bought a collar and put a nice note on it with my phone number. The owner called, very upset. He had no idea that his cat was adopting other families.
We found a kitten while living in the same house. For two weeks, we put up signs and asked our neighbors about it.
Finally we found someone who knew the owner. He was overrun with cats and kittens and didn’t say anything because he was hoping we’d keep it.
That is a cute story!
My daughter had a neighborhood kitty that went back and
forth between three houses. She talked to her neighbors
and they all agreed that kitty was a real charmer. He
lives with daughter mostly full time now.
My neighbor has cat from hell. I’ve feed the little monster
when he travels, until right after I fed her, she attack
me and left an ugly scar on my leg. Just out of the blue,
I’d been watching her on and off for over a year. He even
calls her Mean little kitty now. She bites him every now
and then but he loves her.
