The term "crazy" is a very subjective word - what may be crazy to others may be completely normal to a different set of individuals.
However, many kittens and cats - particularly their behavior and antics - are believed to be crazy by many people. It is well known that cats have their "crazy half-hour" or "cat crazies" where they will hurtle around the house for no apparent reason - and then suddenly stop as soon as it began. This is really very much akin to a small child; children will often run around like mad just to release all that pent-up energy, and it is very likely cats, especially kittens, do the same for the exact same reasons: To release pent-up energy and above all - to have fun! It also serves as a brilliant workout for them.
Kittens can often be confusing in this manner: One minute they are calm and cuddly, and the next they are all little teeth and claws and huge wide eyes. For some new kitten owners, this is where it stops being fun and because they think their kitten is "evil", the kitten is put in a shelter. In fact, it couldn't be more from the truth. Kittens play rough, and it doesn't matter if they are a fellow cat or a human as the playmate. They use their teeth and claws and can hurt if not trained properly. Kittens will often grow out of this phase, but many cats are still playful and will happily play with their owners if there isn't another feline companion to play with.
This is a far cry from a cat actually being crazy. Few cats have mental illnesses and often have a reason for behaving in a certain way - it is down to the owner to educate themselves about their beloved companion's behavior.
