We have two cats, one we found under a bush across the street, and another that we took in from the side yard when Momma Cat had another littler last year. Since then my wife (cat angel) has caught and had all the cat’s fixed, and she puts food at the edge of the woods next to our house where those cats live.
Over the last year those outside cats have also gotten a heated igloo and heated water bowl for the winter months, and a huge outdoor cat tree. Yes, my wife has gone full crazy cat lady!
All those outside cats, although feral, have gotten very used to my wife and myself, and now they are coming up on the deck to watch us.
Our indoor cats are very curious, and no one is aggressive, which is nice, and they are all related. It makes me wonder what everyone is thinking as they sit and stare at each other.
