Cats bite and get abscesses. I hate this and our cat Buttons got himself bit and got a nice abscess. We took him to our awesome vet and he gave me some special antibiotics. I am an expert at shooting pills down cat's throats so I am happy that we can now get him straightened out.
Of course, when Buttons sees me coming he runs... not fast enough yet! The towel I use to swaddle him in is hidden because for sure he will disappear then! I am a great cat bather and swaddler too. People get bad infections when bitten and I so far haven't had that happen. It's still better than a bird bite from Annabelle.
