ear troubles on a budget

she has what seems to be an infected ear. i can not afford to take her to a vet until next week. is there anything i can do for her at home besides keeping it clean.

Go to the pet store & get a basic ear cleanser to wash her ears with. Put it in the ear, massage, then wipe the ear interior with a cotton ball.
   
If it's ear mites, there's several effective & not expensive treatments.
