My 7 yr. Old indoor female cat is suddenly becoming aggressive and wanting to fight and growl at my MALE 5 yr. Old indoor cat. They both are up to date with their shots! She almost acts as if she doesn't know him.

Something is probably going on with her, she is possibly ill or in pain and that may be causing her to be aggressive. i would recommend taking her to the vet for a checkup and blood test to make sure she is in good health first.
