Reason: cats carry a ridiculous amount of bacteria on their claws**, & such infections can kill your snake...so don't give them time to have a "head-start". I think your snake needs both topical wound care and likely needs to be on antibiotics too. CALL NOW, please don't wait.
**This is why when cats fight each other -or you happen to get scratched by a cat- these wounds nearly always get infected.
