Help me keep izzo

Little izzo was found left in a box at an apartment complex in Baton Rouge. I've decided to keep the little guy but I've realized it's pretty expensive for a college student to afford the shots and things he needs. In order to keep him I have to be able to pay for his rounds of shots. The poor guy has staph on his belly and has to start antibiotics to clear it up. If I can't get him the shots and care he needs I can't keep him and I don't want to have to bring him to a shelter. He is such a sweet boy please help me!!!
