Cat
“A cat does not live with you; you live with your cat.” A lot of cat-owners will agree to this statement although there are of course exceptions to the rule.
A cat can be alone for a longer period of time compared to a dog. If you decide to have a kitten and you know you will be out most of the day, it is better to get at least two. A young cat will get bored easily and your curtains will be very good fun to play with.
