Sounds to me like she is saying that if the guy can't give his cats a decent home (meaning "clean up your act, buddy") then he should find someone who will . . . doubt if it would be the girlfriend, since she signed her letter "cat hater" . . .

I've never had a cat that even attemped to jump up on counters . . . if this is a common behavior, maybe I have just been fortunate not to have encountered it . . .

Many, many years ago I visited an old friend I hadn't seen ages. She had gotten into showing/breeding (I forget what breed), and her once meticulous home had turned into CATVILLE . . . the books on her bookshelf had all their bindings shredded, and I remember seeing a cat curled up asleep on top of her coffee maker on the kitchen counter! She had girls tending to the multitude of litter boxes spread all around the perimeter of her dining room. I have no idea how many cats she had, but they were milling around everywhere. The bedrooms had become nurseries, and the basement housed the male stud cats each in a cage. This had to be 20 years ago, and I wonder what ever happened to her and all those cats . . . the counter thing brought back this memory . . . geez!
