Guys, this happened to me. Mine chewed on some kind of shoestring I had lying around the house. I came home to a string coming out of his mouth. I brought him to the vet, they straightened him on the bed and pulled it right out. It went like 20cm inside my cat. Took a couple seconds to pull it out. He couldn't eat for about a night. He was fine the next day. TLDR: NO STRING AROUND CAT.
