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.
1 Use a small amount of cleaner on a cotton ball. 2  Fold the catâs ear back and use the cotton ball to wipe away dirt. 3  Do not clean the ear canal, as this can cause trauma and/or infection. 4  Do not put cotton tips down into the ear canal, because if the cat moves suddenly you could damage the ear or cause pain.
