<human>: About a week ago I decided to sew my own stuffed mice for my cat and my boyfriend's cats.  They're simple to make and I'm too cheap to buy cat toys.  I got the fabric and yarn from a fabric store, but got the thread from my parents workspace because their tailors.  Mind you, they have industrial thread that much stronger than thread that's used for clothing.  

So I started sewing the rats over at my boyfriends place, and the cats love playing with the thread and yarn.  That day I finish sewing 20 mice and the cats go crazy over them.  I left some scraps from the project overnight, but eventually cleaned up.  But days later cats start throwing up everywhere.  We found 20 puke stains around the house.  We thought it was the food because we opened a new bag, so we thought that bag was bad, threw it out and bought new food.  
5 days later, one cat is better, but the other one is lethargic and not eating her food.  We decided to bring the cat to the vet, and he thought that it was either pancreatitis or a blockage in her intestines/stomach. 
Today, they scoped her stomach and saw thread blocking her stomach and twisted around her intestines.  Because the thread was twisted around her intestines, parts of the tissue died.  They got all the thread out, but they aren't sure if she'll get better.   
So now we're in limbo, on whether or not she survive from this...

Give me the gist of the text in a nutshell
<bot>: My boyfriend's cat ate scrap thread and now part of her intestine has died.  We don't know if she's going to get better.
