If you’re not familiar with the term, splooting is when a cat lays out flat on their stomach while having both of its hind legs spread all the way to the back.
There is also a name for cats keeping their fore and hind legs tucked in under them. This is called "cat loaf" or "cat loafing" because they look like loaves of bread.
There are two main reasons why your cat is splooting. First, when it gets into this adorable position, it is either because it wants to relax or because it wants to cool down.
As all cat owners know, cats are incredibly flexible, so the splooting position is nothing more than stretching. It is also a very comfortable position for their backs, which is why cats love sploot.
When cats lay on their bellies with their fore and hind legs spread out on the floor, they could also be trying to cool down. They use this position to expand the contact area with the floor, which is cooler.
When your cat has its forelegs spread out in front of it and its hind legs stretch behind itself, that is the complete sploot. That is the maximum level of relaxation for the cat's joints, muscles, and spine.
