Whats wrong with my cat ? is it mange?

i know how frustraighting this is i have had to many cats to count and experienced almost every cat sickness out there.you are probably dealing with mange or a fungal skin thing or possibly both.the angry scabs are from him itching perfusley.it is probably mange though.if it is they will give you some meds and a anti fungle wash.your cat is gunna wear a cone to prevent him from itching.because it is a parasite it is highy catchy.you should seperate your animals asap.if they were near each other than you better watch for development of mange in your other animals.be wary,the treatment of this for your cat is costly and if your other animals get it,your looking at almost or more than a grand.humans cannot catch it but keep your kids away from them.the meds are daily so make sure u dont miss any doses cause parasites reproduce like crazy.
