Hello everyone. I am a foster parent for kittens from the local shelter, this is my 3rd batch, but this batch isa little different. The last two sets were very friendly and I afraid of people, while these kittens cower at every movement and sound. They'll let me pet them after I've laid or sat down and waited a few minutes, but in worried they'll never warm up.. I've been playing with them and sitting with them, petting while I'm feeding them, but I'm wondering if there's anything else I can do to help them become less afraid of people and ready for their adoptions.. I have read that there are some windows of time where human socialization is most important, but I'm not sure if we've missed those.. They're probably about 6 weeks? About a pound each.
