Cats have a sense of humor and often have an expression of laughing. They do not enjoy a joke against themselves, however, nor do they like to be laughed at. They hate to be teased, and they very rarely learn to do tricks just to amuse. But if their human is having fun they like to join in, and they will certainly grim broadly at a joke against him. Most cats are very good at looking after themselves, and, on the average, have a life-span of fourteen to fifteen human years.
Cats seem to have some miraculous escapes, and they also treat life with the greatest respect.
A cat will not rush into a situation without first examining its surroundings. Open the door to let it out, and it will size things up before it leaves the safety of the house. At night, it will hesitate while its eyes adjust to the darkness. Its reaction to sudden movement or noise is so swift that it can usually escape threatening danger, just as when a cat falls it nearly always lands on its feet. Cats and Dogs A cat will only behave aggressively to dogs when they pose a threat to its territory or to its security.
