I have what I think it a really big problem with my male cat Rascal. He got into a fight awhile ago and got a minor flesh wound on his head just below the front of his ear. Well for a while it was fine but then he got outside again and I think he may have re-opened it while escaping. It got infected and was oozing pus when by the time I actually noticed it last night. By then it was pretty bad and his ears were fevered, but he scratched it open and it started oozing from that. I went into the bathroom with him and was keeping it clean with just water (I don't know what else is safe to use) and wiping what pus came out. Today I figured I'd leave him alone for most of the day because his fever broke and his ears were back to their normal temperature. Problems started again early in the day when he broke it open again and I had to hold him down to keep it clean. Well he was scratching it in his sleep and it pulled partly off and not wanting it to get worse I pulled it the rest of the way off and a hard core came out with it. He now has a small open wound on his head about a centimeter and a half deep and a centimeter wide. What on Earth can I do at home for him until I can get the money to take him to the vet? I'm really worried about him =( he's acting mostly normal but he's quiet and sleeping a lot more which is the not so normal part. He's eating, drinking, and using the litter box fine but I don't want to make this any worse than I already have =(.
