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.
This disorder usually results from infestation of the ear canal with infectious agents, such as yeast, bacteria, or ear mites, and leads to inflammation. Owners should also keep in mind that a catâs eardrum thickens with age. Thus, hearing difficulties and potential deafness are often found in geriatric cats. Most acquired feline ear disorders, including otitis externa, can be treated with medicine, says Dr. Flanders, although surgery may sometimes be the only option.
