We rescued baby squirrels on Monday. They have been doing great and are good eaters. This morning the little one was making a clicking noise and didn’t have much of an appetite. We only had amoxicillin on hand. I did the math to ensure a proper amount was given. She refuses to stay near her heating pad. She weighs 63 grams. She is very tiny and her eyes aren’t open yet. Her brothers are and he weighs 93 grams. Is there a reason she is refusing the heat?
