Cat bites - even small wounds that require antibiotics. The germs in a cat's mouth produce serious infections and are deadly to rabbits unless treated promptly. Broken bones - usually in the legs or wings. The skin may or may not be broken. Puncture wounds - deep wounds from bites or gunshots.
Antibiotics are necessary.
Maggots - Flies lay their eggs any open wound or anywhere on weak animals. They can hatch in 24 hours. Resembling clumps of sand, the eggs adhere to the fur. Remove them at once. The maggots can do considerable damage to healthy tissue if they hatch.
