I'm glad to hear that Weemer finally pooped some of it out. My Pearl also ate some red elastic string and I was unaware of it until I saw her pooping it out. At first I thought it was blood in her stool. I later found the toy and threw it out. She was a very lucky cat. Now I make sure that all of my cats toys are safe. I even cut off the tails of the mice that I buy them because they also love to eat these.
