Cats are great. They don't need to be walked or let outside to do their business, and they take care of cleaning themselves. All you need for your indoor cats, aside from food, love, and toys, is a litter box. And, of course, there are several types available depending on your needs. The most important thing to remember, though, is that the box needs to be big enough that your cat can turn around in it and cover up its waste. Take into account how big your kitten will grow and plan accordingly. And remember your litter box is only as good as the litter you put in it.
