When I was younger we adopted a kitten from a rescue group. They had rescued him from euthanasia at the local A/C for being 'vicious.' He had been owned by a lady and her 2 year old at 6 or 7 weeks old. When he scratched and bit the baby, he was deemed dangerous. This same animal control, until they remodeled where you couldnt tough the pets, would litterally post large warnings on some kittens cages labeling them as dangerous bite cases that were unavailable for adoption because of it.
