Pets

but I found with any feral and skittish cats I've had.... if I sleep on the floor with them over a night or two they tend to warm up pretty quickly.
I don't know if this would happen every time but it's happened with 4 cats over the years.

I could never fully get one feral to not try to eat my hand (it was her mission in life to chomp down on it - and never did get to live that dream) but she became the biggest snuggle bug as long as I always pet her from behind her head. If she saw my hand come at her it was attack time.

If you can't try that, maybe you can pass it on to someone who's willing to foster or adopt.

Good Luck!! Sounds like you have your hands full.
