Hi, I've had lots of kittys spayed and neutered and I notice after they shave a female for spay surgery it takes a long time for that fur to grow back, more so than anywhere else on the body, they can look necked and weird for many months after. Just make sure she's eating right and acting right, check her for fleas if she is losing hair on her back, make sure she isn't stressed because stress can cause a kitty to start losing hair. I don't know about mange in cats but I would put some spot flea treatment on her, you'd be surprised at the trouble a flea can cause.
