Do not pull the string! If the string is long (12 inches or more) cut it down so she won't get it caught on anything. If it is wrapped up in her intestines it could rupture them and kill her! You need to get her to the vet ASAP. And don't panic. If you're stressed, your cat can sense it and also become stressed. I had that happen to my cat two weeks ago. She was rubbing her butt on the carpet. She ate thread and had it coming out her butt. I IMMEDIATELY called the vet and he said to bring her right away. He pulled it out and then prescribed an antibiotic and Albon to make sure if she had any thread left in her it would help her poop it out. She's been fine and no other thread came out. Good luck and let me know how you make out.
