Cats
Some cat owners notice their pets' unhygienic habit of removing pieces of food from their bowl and dragging them around on the floor. This can happen to both small kittens and fully grown cats. Many don't understand why cats prefer to play with their food, attributing it to their pet's pickiness. But in fact, there's a scientific explanation for this habit.
Cat owners are debating the benefits and harms of bathing their pets. Some argue that regular bathing is essential because germs accumulate in their fur, and when they wash themselves, all that dirt gets into their bodies and causes health problems. Others believe that cats' meticulous cleanliness precludes frequent bathing and allows for water treatments only when absolutely necessary. The truth is, however, somewhere in the middle. Cats shouldn't be bathed frequently, but why not bathe them a few times a year?
