One of the nice things about cats is how individual their personalities are. Also one of the difficulties, because all the things that made you a great partner to one cat just piss off another cat, but they are all great in their own way.
Had two brothers from the same litter. sometimes it was so obvious they were brothers, like when they'd sit in an identical pose and watch me with hopeful eyes if I was cooking.
Other times they were nothing alike. Different preferences for food, for attention, for the most comfortable position for a cuddle. Lovely boys. They did have the same vocalisations though, only I could tell the difference just from hearing them!
Or he is being fed by the neighbor. It happened to us, we started to ferry worked because it cat stopped eating, only to realize later that our neighbor was feeding him too.
One time I was studying for the day at a dog owners house and I was asked to let the dogs outside in the garden at around midday. They didn’t say to let the dogs back in, nor did it ever occur to me that they wanted that. They started to get quite loud in the afternoon.
Only really felt that way about the ones that would stay outside. If I didn't see one of the cats I've had that just liked to stay inside, I'd be concerned. The last one usually would just slip in behind you as you were leaving the pantry or bathroom and get locked in.
This is not my neighbour. If one or both of her two beauties do not come prancing around the corner within five minutes of being called, half the village will be mobilized for kitty patrol.
