Gee whiz! Some people have no concept of limitations. I'd say *nobody* can keep about 100 cats in a small house. I had 8 in a big house with acres of land for them to run in.. and that was a challenge to keep up with. Vet, food, fleas, bites, etc. Your Saxon was lucky.
Sad. We have this kind of thing in our area too, it comes up every year.... there'll be some new animal-hoarder brought to court. I know they often mean well, but ... ???
