Because cats have no collar bone they can easily squeeze through anywhere their heads fit into. These cute animals that spend 16 hours a day sleeping are also very fastidious when it comes to cleanliness. They spend around 30% of their lives grooming themselves. Cats are also highly intelligent animals. A cat released a long way away will still be able to find its old home. They also have powerful reflexes allowing them to twist in the air and land on four feet when falling from high up.
