I believe it! My cats played like this often! It reminds me of my son and his best friend wrestling around as teen agers. Anyone who didn't know them would have sworn it was a real fight. The teeth and claws just touch, but don't penetrate.
Gandalf and Mooch do the wrestling thing too... but it's extremely funny with them as Mooch is an overweight adult cat and Gandalf is a very skinny kitten (well, about 8 months)... Gandalf takes flying leaps at Mooch's head and he just pins her on the ground... very laughable. :lol:
