Thank you so much for asking about my kitty! Luckily it was just a cut, or scratch that got irritated and a bit infected. She said he and Chloe were probably playing rough and he got bit or scratched. She gave him a steroid shot to ease the irritation, an injection of antibiotic plus some more liquid antibiotic to take home. It looks better already. even seems as if the hair is starting to grow back already! :)Thank you so much again, for asking!
