What is wrong with my cat?

It is probably ear mites. There are many over the counter medicines for this, and it can't hurt to try one out.

Head shaking and head tilting are usually caused by an outer-ear infection called otitis externa. Caused by bacteria, yeast, or other organisms, this condition is particularly common in dogs with large, floppy ears because the insides of the ears get hot and humid, creating a perfect environment for infection. Pets with ear mites will also shake or tilt their heads. Dogs aren't immune to ear mites, but they get them much less often than cats do.

Food allergies are a common cause of ear problems. Unlike people, who often get upset stomachs from eating foods that they are allergic to, dogs and cats can get downright itchy. When they aren't scratching, they may give their heads a quick shake for temporary relief.

In cats particularly, itchy ears are often caused by ear mites, which are tiny, crablike parasites that occasionally take up residence. When the mites scurry around, the ears can get intensely itchy.
