While some people can't imagine their lives without pets, the others can't understand the reason why pets are so popular. And perhaps they are right - if you have a cat or a dog you have to feed it, keep it clean and healthy, hide all of your favourite clothes and shoes as far as possible and, of course, do the hoovering to clean the hair they lose. But this is the key to the question why pet owners need pets! Believe it or not, but if you have a domestic animal, you can forget about doing such boring part of housework as hoovering. Guess it's impossible? Prove youself!
