Hi, this thread jumped out at me as I had a major crisis involving the ribbon they use to tie onto balloons. I have a Himalayan that chewed up a portion of this nylon thread and I had no idea. Well he soon began vomiting and there was some blood in the vomit, he was completely comatose acting and miserable. With vet visits, they determined that the intestines were not moving normally. Well to make a long story short, surgery was necessary and sure enough a chunk of nylon ribbon was extracted. Gizmo made a full recovery but it was a horrible experience and very costly. Now when I see those ribbons I race to throw them in the garbage if anyone ever brings a balloon or present with that sort of thread on it! I'm so glad you posted and started this thread. It's good to be aware of this life threatening hazard to cats.
