Hi , recently found a baby squirrel while walking my dogs. He was on the ground and it was already dark ,and getting cold so we took him in. I believe he is about 5-6 weeks old. I am doing my best to feed him with a pipette until I can get a syringe tonight. He is ravenous, I try so hard to make him go slow. My question is how do I know if he's getting enough. After a feeding he will root around for more and once he realizes there is no more he goes right to sleep.
