Pet's info: Cat | American Shorthair | Male | neutered | 2 years and 9 months old | 10 lbs
My cat's fur has been thinning on his back legs and lower back and now has started getting big sores only on his shoulder blades. It has only been happening for a few weeks now and I'm not sure what caused it or how to fix it?

It is difficult to tell from a photo but these look like draining wounds, like possibly an abscess that had opened. The most common cause for this would be a bite from another animal. You don't mention if your cat goes outdoors but if he does that would be my first suspicion. From the limited amount I can see here I would recommend a vet visit because he may need to have these flushed and be placed on an antibiotic.
