Our vet stressed all those kinds of dangers when Edna was a kitten. He said he did surgery all the time on cats that liked the "eating spaghetti effect." Even our vet tech had his own cat swallow a shoestring and then bite it off at the shoe. He didn't even know it had happened until the cat became ill with the impaction. Who doesn't go out and get one of those cat dancer things (feathers and bell attached to a string and stick) when they have a new kitten? That should be played with only when supervised and then put away when you're throughIt was good advice and Edna is now 18 years old.
