Excellent. We have the scars. In the end I just bought that liquid stuff that you squirt onto the back of the neck!

Regarding the dirty ears, your cat may have mites. They look like a brown crusty substance.

Check inside the ears every week and if you see a waxy residue, wipe it off with a cotton ball moistened with a small amount of feline ear cleaner or baby oil. (Never use a swab on a stick; if your cat moves suddenly, as he is wont to do, you may injure his ear canal or eardrum.) Hold the earflap gently and dab carefully with the cotton ball. If your cat fidgets during cleaning, restrain him as you would when cutting his claws.

As for the pill, I mix a small teaspoon a wet food or flavorful food with the pill and they eat it quickly.
