I was petting my cat today when i noticed a small bump by his ear and under his chin. I tried to look closer and it was a red bump. Does anyone have any idea what that could be ? i dont have any other cats. Its a small bump with a red in the middle like a small scab. Im thinking it might be fleas? any ideas? he has been scratching himself there more than usual. from what ive read its a flea allergy bite.
