Grumpy Tortoise Repeatedly Headbutts Fred The Cat!

In Sweety High's latest Video Pick Of the Week, a funny little tortoise seems to have a grudge against a cat named Fred, and it just won't let go!

The video begins with the tortoise repeatedly headbutting Fred the cat in his back. After a few strikes, Fred gets fed up and tries to get away, but every time he does, the tortoise isn't far behind to bump into Fred again and again!

The entire video features more than two minutes of the frustrated tortoise relentlessly pestering this poor cat! 

What's he doing? We have no idea, but a quick web search also turns up videos of tortoises headbutting vacuum cleaners, mirrors, feet, dogs and a lot more!
