The amount of work, price and time that goes into having a friend creature varies from family pet to pet, so let's take a look at different kinds of pets, and which might be most suitable for you.
Cats are incredibly popular as dogs. They are also beautiful, fluffy and affectionate, but a lot more self-reliant than pet dogs. Most cats can be still left alone all day long (or even right away) without ill-effect. Felines tend to eat much less that canines (with the exception of the toy variety of dog), and they don't require double daily walks, intensive training, or constant guidance. Pet cats and kittens are a breeze to house-train, too. Just give them a litter-box and some litter tucked away in a tranquil spot of the basement, and you can rest assured your cat will litter educate itself.
