My cat Scabbers just came home with a worm hanging out his backside. Still wriggling. He's not due to be de-wormed for another month! I shrieked and tried quickly to pull on some disposable gloves and grab loo roll. When I got back in the sitting room he was licking his anus and happily swallowed the worm. 
This is the cat I let sleep on my pillow.
I will not sleep easy tonight.
