I have a 7-9 week old gray squirrel who has been on esbilac formula, the only thing is that it’s been the second step formula which is puppy weaning formula so last night I changed his formula to the esbilac regular puppy formula and I did half of old and half of new and since last night he’s been on the 50/50 , he ate this morning and this afternoon but now he won’t eat! He’s constantly sleeping and not really active he has been drinking out of his water bottle. He does seem a little bloated as well. Last thing he seems to be breathing very heavy and feels warm. We have a vet appointment in the morning but I’m worried about him!!! He’s definitely not himself. Can someone help just until we make it to the vet please, I’m so attached to this guy . Please help!!!
