About 4 days ago we rescued two baby squirrels approximate age is about 4 weeks. The female is doing great. The male is not eating well and when he does it comes out of his nose. I turn him upside down to get all the milk out but I think he has aspiration ammonia. I don’t have amoxicillin, but I have cephalexin(500mg) and Clindamycin hcl(300mg). Would either of these work in lieu of amoxicillin.
