When it comes to pets, cats are pretty self-contained. Keep them supplied with plenty of fresh food and water, and they'll love you forever. They don't require a lot of hands-on attention, like dogs tend to do. In fact, if you try to pay too much attention to a cat, they may reward you with a stern look and a tail flick. However, when you need a snuggle, they'll be right there to curl up in your lap – as long as it's their idea.
