My cat is loosing hair around face and ears, what do I do to treat her? What can it be? Help!

Yes I think I'm going to take her, it's just that one of my friends said that it could be some kind of mange like her dog she suggested I go to Petco but they had already closed

I agree with the other response of taking the cat to the vet that is your best option!

What is her age? It may be better to take her to a veterinarian.
