Just a very late note to your problem, Megs.

My vet recommends any triple-antibiotic ointment for injuries such as you described with the toenail. Unless your bunny got a hold of and ate the entire tube of ointment, and yuck!!! he would not do that , the over-the-counter triple antibiotics are perfectly safe....I think Neosporin is a triple antibiotic, I just usually buy the store brand.
