How can I tell if my cat has mange?

My cat has recently been venturing outside despite my attempts to keep her in the house, since she last went out and came back I have noticed hair loss on her ears and today i came to discover a large patch and a smaller one of missing hair on her leg, there are several red marks and sores and little scabbing on the skin where the hair has gone missing…. do you think its mange or something else?

Sounds like your cat is getting into fights with other cats. You might want to bring her to vet to be sure. And don’t open the door with her near it, if she goes near it squirt her with a squirt bottle. She doesn’t need to go outside, doesn’t seem to safe.
