^^ wholeheartedly agree. Cats are wayyy worse. I wouldn't worry too much. There are very few diseases that can affect both species. I'd be more concerned with any bacteria on your skin working its way into the wound. Just keep it clean, toss some triple antibiotic ointment on it, and like everyone says, if it changes/worsens, get a doc to check that bad boy out. And maybe get some safety needles next time
