Patch of missing fur on my cat!?

can anybody tell me what this could be? it's not ring worms. but my cat I just received as a Christmas gift has a patch of fur missing on her back leg that almost wraps around her leg. it doesn't hurt her & she just got spayed she even has her stitches on her stomach still. her front leg has a patch of hair missing but I'm assuming that's from where they had to shave and give her an IV. HELP! I don't want her to be ill. she's under a year old if that helps. updated on all her shots

They shouldn't have shaved her there for a spay.  Keep an eye on it and when you take her back to have her stitches removed, ask the vet.  If you notice it getting bigger or changing, then get her to the vet sooner.  Congratulations on your new kitty!

Have you noticed her grooming that area a lot? It could be from anxiety.

No she doesn't itch or clean that area at all. That's what's odd. it doesn't bother her that's why I guess I'll wait for it to heal
