I rescued a little grey yesterday, 5-7 weeks old. He was infested with fleas, but I spent a couple hours picking them off with my fingers, I also changed his bedding material about four times, the fleas tend to jump off of him and onto the bedding so I figured that would be a good method to de-flea him, this morning I only picked a few off of him so thats getting better. His first feeding went well, he grabbed the syringe and drank 6cc of puppy formula with gusto. This morning, he is lethargic, doesn't move much and only wants to sleep. He makes little clucking noises. I can't tell if it's pnemonia or not, his clucking sounds like a baby version of adult squirrels clucking from the tops of trees. But his clucking is week, is he tired, or sick? He isn't intersted in formula this morning. This is the first feeding he has refused, but he's so sleepy, I'm concerned. His eyes are open wide and clear, but he will fall to sleep in no time flat right in your hands. When he rest sometimes, he just puts his face down in our hands or in his box, and that worried me too, he doesn't adjust his position right away. I've got him in a box, half on half off a heating pad, feeding him the puppy forumula the experts recommend (don't remember the name, starts with an E), he hasn't peed or pooped yet although I've been stimulating him with a Q-tip dipped under warm water, (I've only had him about 12 hours). If there is a problem, I want to get him treated early, problem is it is Saturday, and I don't have any vets nearby open on weekends. I know it's hard to tell without seeing him, but if he is sick, will he make it untill Monday?
