Caring for the Ears:
You do not need to help most hamster to keep their ears clean. In fact, hamsters seem to take great pride in giving themselves a daily cleaning. The truth is, hamsters will spend up to 20 percent of the day cleaning themselves.
If your hamster’s ears seem red, inflamed, or infected you should take a closer look. You may also want to check the ears if your hamster is scratching excessively. Ear mites are another potential problem for your hamster. You can usually tell if you hamster has ear mites because you will see the small black parasites. If left untreated, they can result in serious issues for the hamster.
