THE THING HAPPENED TO ME!! A cat came in from outside and totally made itself at home! I gave him/her some food and it thanked me by letting me pet him :D He even ventured around my desk!
My cat Sora totally didn’t mind having him inside,until it got close that is.
I used to have another cat that looked just like this one, and was from Sora’s first/only liter of kittens. I think she probably mistook her for her lost daughter :(
I started leaving some food out or it, and he has stopped by almost everynight!
