Yesterday, I found a baby squirrel in neighbor's driveway. He appeared to have fallen from a nest but I couldn't find one nearby. He has a couple of abrasions but seems to move around normally. I brought him home & have been researching since then. He appears to be an Eastern Gray & maybe 5 weeks old. I got bottles & puppy milk. I got a carrier for him. He doesn't seem to be eating much & he sleeps a lot. It could be normal but since I'm no expert, I don't know. I used a food scale to try to get his weight & it was a bit difficult to get him to stay on it but the reading I got appears to be 49 grams. His eyes are open but he seems rather small for a 5 week old, based on the research I've done. I'm mainly worried about how much he's sleeping & I'd also love some guidance on whether I'm feeding him the right thing & how much of it I should be giving him. I'm gonna try to attach a pic also.
