my pet rat

Question
my pet rat chewed his toe's off one foot what should i put on his foot, would first aid spray work

Answer
You need to find out why he chewed them off. Don't use first aid spray - clean it up with a mild antibacterial soap and water, than coat it with a thin layer of triple antibiotic cream and leave it at that. In the meantime, watch him very closely and be sure he doesn't start on the other feet!
