Can cat's Quite Scratch her Itch..

Rumble/cat itch

Your cat might be scratching her ears because she's having an allergic reaction. Cats can be allergic to many of the same things as humans—dust, pollen, mold, grass, insect bites, food, and medication. Allergies cause ear infections, and red, inflamed, itchy ears.

To treat itchy ears in your cat, take it to the vet if your cat is scratching its ears frequently, or if you spot the signs of an infection. Your vet may recommend cleaning its ears at home with a product made specially for cats. Alternatively, they may sedate your cat in order to remove polyps or growths in its ears.
