The name of this post is the exact name of it's youtube video - it really is quite hard to describe using less words! So there is this cat (Max-Arthur), who wears a shark outfit, whilst sitting on a Roomba (vacumm cleaner) whilst chasing a duck and then the family pitbull (Sharky) comes in wearing a hammerhead shark costume. There's also dramatic moments of the animals starring at the camera which makes it one my favourite cat youtube video ever! I might even go as far as saying IT IS my favourite!
