Just for future reference: anytime an animal is attacked by a cat, it is going to need to see a vet and get a course of antibiotics. Cats have so much crud and germs in their mouths and claws that it is a given that any animal bitten by one is going to get an infection. With rabbits and hares, it is always best to let a vet handle it because rabbits and hares have such delicate intestinal flora that if not administeredd carefully, the anibiotics can sicken and kill them as thoroughly as any cat could. Many vets will take in wild animals for free and have them rehabititated by a licensed wildlife handler; this is really the best route to go.
