Please be careful who you give the kittens away to. I've seen too many irresponsible people take horrible care of their animals.
Make sure they go to good homes.
My new kitten, Tolstoy was left on the doorstep of a no-kill animal shelter. He was really a great find for me. He's a solid black full-bred main coon
Anyhow, I'd turn them over to a no-kill animal shelter if I couldn't find them homes.
Start asking around right now though.
