My cats LOVE to eat things they shouldn't so we have to keep a careful eye out for them. For example, I was making a smoothie in the kitchen with my new smoothie maker I got from my bridal shower and I left the computer room door open. Well there just happens to be a balloon in there and when I came back in, half of the string was gone and there was a lovely pile of string puke on the ground next to it. I know it was Pumpkin that did it, in fact she is still vomiting the pieces up. She loves to eat string and plastic. All I have to say is thank god it comes up and doesn't cause a blockage!!
