I had an old street cat I sort of domesticated. He had a kinked tail, some missing fur, a chipped tooth, and a piece gone from one ear. I also had a moron neighbor with 2 stupid beagles.
She’d let the beagles out every morning to defecate in the breezeway. Then they would tree my cat, for just a second, until he tore them both up at the same time. This happened every morning until she got evicted. I eventually bought a house and converted him into a housecat. He hated it at first but finally got used to air conditioning and meals he didn’t have to kill.
They kind of like not having to fight anymore, too.
When we moved down to South CA, our indoor/outdoor kitties became indoor only due to coyotes. Our gray Tabby, who used to fight (had that little piece of ear missing!), seemed so relieved that he never even tried to bolt through an opening door.
