jinx, don't get your hopes up. That's what a vet will tell you. Although, I've raised kitties and puppies by hand and never lost one.

First, don't feed them cow milk (lactose intolerant). If you have some soy milk that's okay, until you can get some soy-based baby formula. Pet supply stores should have little bottles and nipples. Maybe look into some glucose/vitamin paste.

Mammals need warmth and contact. Bundle and snuggle.

I know that for kitties, they can't poop or pee without mama licking their parts (true story) so you have to swab their bits with a warm, wet cotton ball.

I also want to add that a squirrels might carry some nasty germs, so I would look into a good all-over bath for the little bushy-tailed rat.

Edit: How to feed a hungry, wild rascal. Wrap in a hand towel with only the head sticking out, wet the mouth with formula, and tease with the nipple until they get the idea. DO NOT squeeze milk down their throat!
