Fucking idiot.
M&S had some cupcakes on yellow sticker so I bought a pack of two and settled down to eat one with my cuppa when I got back. Bastard Cat seemed very interested when I popped wrapper down, but I thought he was just going to lick the leftover hundreds and thousands etc.
I have just looked and he has actually eaten 90% of the paper cupcake wrapper 
He's an outside cat so I won't know if it affects his digestion.
Please tell me I don't have to go to the vets?
