CATS can’t climb head first down a tree because every claw on its paw points the same way. To get down from a tree, a cat must back down. Cats don’t have sweat glands over their bodies like humans do. Instead, they sweat only through their paws. Female cats tend to be right pawed, while male cats are more often left pawed. Interestingly, while 90 per cent of humans are right handed, the remaining 10 per cent of lefties also tend to be male.
