We have 4 kittens, newly borns about 2 weeks old and the mother cat has ran away? I'm not sure but it's been about 1 day since she came back to the house to feed her kittens and what not. I'm sure they're starving and I've tried feeding them with generic nipples and powdered milk, also tried cow milk but no luck, I literally would have to pry their little mouths open for them to drink it, what should i do?!
