My Cat got bitten by something last night

He wretched his hind leg which was later bitten by something when he got out of our porch and into our backyard, we're hoping to get rabies booster shots and antibiotics so the bite wound doesn't get infected, my sister came crying into my room this morning and told me about it as I was waking up. I hope my cat gets out of this mess and become the same silly cat he was before again.
