Is it ok to touch new born baby kittens
Yes, that's fine. You should avoid touching them too much though.
Well, Probably not, because they are delicate, but if you're careful enough then I guess it's okay. Also, If the mom cat sees it as okay, then you're good to go. I hope this helps :)
If they are wild no because the mother will abandon them but if it's your cat or someone you know then it's ok
Yes, but not too much.
I've had newborn kitty's before, and you should probably just pet them for now until they get older and not too much.
