Please don't let your kitty play with thread. My friend had a beautiful Himalayan kitty that was playing with a spool of thread. She unwound it and managed to swallow a lot of thread. The cat wouldn't eat and she started vomitting. By the time they got her to the vet it was too late to save her. The thread wrapped around her intestines and even though the vet did surgery, it was too late to save the kitty. Cats should never be allowed to play with thread.
