One of my cats, a two year old neutered male, chews and swallows shoelaces,ribbon, yarn, elastic hair bands, plastic bags and wrapping, styrofoam, and rubber such as ballons and cleaning gloves. He chewed on my embroidery a week ago and swallowed the needle. A trip to the vet ensued with x-rays, fortunately it was already in his colon and a subsequent x-ray revealed he had passed it safely. Does anyone have any ideas how I can stop this behavior? So far I have been using bitter apple on shoelaces and trying to be meticulous about keeping everything else away from him. Clearly I failed with the needle. He is a great cat in every other way. Thank you for any suggestions.
