Today I have by accident thrown a AAA battery into a bucket of water. I fished it out of the water immediately (within 20 seconds or so) and nothing notable had happened and the battery is still full according to a battery test device.
Cats Scratching Ears with Parasites. If this is not the issue, then it may be related to parasites alone. Check your cat's ears for signs of ticks, fleas, and mites. These parasites can cause obsessive scratching, as the cat makes a desperate effort to relieve pain and discomfort. If your cat is not allergic, try using natural tick or flea repellents (or mite repellent) if that seems to be the issue.
My cat has been digging at her ear for as long as I can remember. I have taken her to the vet numerous times and they have found no excessive waxy build-up in that ear, or any type of ear parasites. She shakes her head quite a bit and Iâve caught her aggressively digging at it several times.
