All my cats are up to date on shots, luckily. Otherwise I'd be screaming due to the fact I can't afford a vet for a bit.
I'm working on catching Mr. Feral. He's clearly not been fixed. I work with animal rescues from time to time (cats and dogs only). As soon as I catch him and spay him they're going to help me see if we can find an adopted feral colony to integrate him into. Being tossed into a strange area with strange - and violent - house cats isn't not a good idea if you're feral.
Luckily I have syringes of all shapes and sizes. I'll see if I can round one up to clean the wound. Should I like... Stick it inside the wound? (A non needle type) Wouldn't that hurt the poor chick?
I can't since it's not my chicken.

The kid is only 12 years old, and his parents don't see the point. They're of the mind that a chicken is dumb, and if it dies, it dies. I'm working on a solution to that as well, but in the meantime I at least want to do what we can.
I've been bitten down to the bone several times by my cats. I'd begun to think that cat saliva being bad was a myth. Of course now that I've gotten lazy it proves me wrong! I have a syringe. It's the non needle kind. Should I poke it inside the wound?
I'm guessing it's very, very infected.

The fact that both my cat and the chicken caught it is worrying. I'll keep flushing it out.
Side question, why would it have looked 'fine' before the pus came out? It wasn't swollen or tender at all until the scab came off. At least with my cat it swelled up right away. The chicken would have had it for a few days before the scab came off and the swelling/pain began.
Now I'm worrying for both of the animals. There is NO way I could get either of them to the vet before next week - I'm lucky I kept my water on this week. I know I tend to focus more on my cat, but that's because he's right in front of me and I have to go visit the chicken. I asked on a cat forum and they pretty much said "get it to the vet or you are a horrible human and shouldn't own animals." Ugh. I'm on a mission to help these two beautiful creatures out as much as I can until I can get to a vet. I figure if nothing else, I can figure out how to help the chicken (who really needs a name!) while I deal with my own creature.

No 12 year old deserves to watch an animal suffer because his parents are weird.
And I'll catch the feral so this doesn't happen again.
