I'm really sorry to hear that you refuse to take your cat to the vet.

I think if he already has lost some teeth it would mean dental problems or some other dental related issue. As Anakin's Mom mentioned, he may soon refuse to eat because of the pain or discomfort. I don't think brushing his teeth will help at this point since gum disease happens over a long period of time. Plus, the ear condition could be a number of things which should not be evaluated by us online. Your cat really needs to see a vet.

If your not going to take a cat to the vet when he is in need of medical guidance please don't consider taking on another animal into your household. It's really not fair to the animal to be cut off at such an age, because so many medical conditions are age related and should be looked after.

Would you consider looking for a low cost vet clinic in your area?
