Doc will she can not go against her parents.. she is only 14 and we do not know what her punishment would be. So please help her in another way

I will offer to pay for the treatment,, But she has to make effort in some of this.
Becides her parents in all legality clearly in default at best with animal cruelty/by cause of neglect.

I tried to email her I'm just afraid they will let it die. Thanks.

I just hope it was someone trying to get us all worked up and not really a situation at all.

Well I read and reread the last post and I'm thinking... maybe or just some cheap adult looking for a cheap way out... they got a few tears form me

My childhood cat always came home with wounds from either fighting with other cats or from blue jays pecking holes in his head, and I always cleaned the wounds with peroxide and a topical antibiotic cream (Neosporin is a name brand, but generics are much less expensive), and both products being readily available in most any house's medicine cabinet. Before cleaning, I would pick the scab and squeeze any puss out first, and then start the cleaning process. It may be too late for that, but it is worth a try for a last ditch effort. Your cat's demeanor sounds very much like my cat, and he would let me clean him up without too much trouble.
As far as a phone call, I agree with DocWill there really is no excuse, if indeed this is a true situation. Pick up a phone book and start calling around for help. If you explained your situation, most non-profit, no kill shelters would arrange to pick up the cat at your house. I know the place I volunteer for would.
