32 thoughts on â10 Greatest Empires in the History of Worldâ. 1  For some reason I feel like I need to disagree that the U.S. is not an empire.

How to Safely Clean Your Ears. Normally, ear canals are self-cleaning and should not need to be cleared with any foreign devices. Trying to clean the ear with cotton swabs or other objects can actually cause problems by pushing the ear wax deeper into the ear canal.
Cleaning the Ears. You donât need to clean the ears if they look normal. A catâs ears have an amazing ability to clean themselves. If you clean them too often, especially if they donât need it, it can damage the ears' health. If the ears have a mild odor or look a little dirty, moisten a cotton ball with a mild cleaning solution recommended by your veterinarian and wipe them out. (Never use alcohol, which stings like crazy and can dry out delicate ear tissue.) Be sure you donât go any deeper into the ear than your first knuckle. Tip: Donât clean your cat's ears with a cotton-tipped swab.
