how much does this cost? I want to be safe and I don't wanna do something to hurt her, but I also don't wanna pay an expensive vet bill just to be told to go by drops.
You might want to try getting her fixed up at your local ASPCA. My cat had ear mites and we brought her to the animal shelter to get her fixed up for a relatively inexpensive price. They helped us out to save the animal. Ear mites are parasites and should be taken care of ASAP to avoid infection and/or possible death. Good luck!
