Your cat would be very angry and aggressive if it had rabies. If it was attacked by an animal that you believe had rabies, notify your vet. Also, your cat should be fine if you had its rabies shots. Take it to the vet to be sure.
The most common symptoms of rabies are foaming at the mouth, skittishness, and hallucinations. The best thing to do for your cat in case of rabies is to try and coax them into a cat carrier so they can be taken to a vet for treatment.
