Technically, it wasn't a shoelace. It was a waist-tie that went to one of Kathy's sweaters. She didn't want it, so it became a cat toy, because cats like dangly things. But for all intents and purposes, it looks like a long athletic shoelace, albeit without those plastic things on the end.
And some time yesterday, it became a cat snack. I've previously mentioned my cat Pedro's sharp intellect, so clearly it was a well-reasoned and logical decision to eat something that's more than a foot-and-a-half long and not food.
Thus we were greeted with much regurgitated cat food on our carpet upon entering the apartment. And a crusty foot-and-a-half long regurgitated shoelace. Unfortunately, we're pretty sure that the shoelace was longer than that, and our suspicions are emboldened by the fact that he's not hungry and can't keep much water down.
Late night animal emergency room x-rays ($285 cha-ching!) mostly show that a shoelace is not really detectable by x-rays. It might be in there, but the vet didn't see strong evidence of it. Pedro still spit up water at 5am, which makes me think it's in there and blocking the passage.
Worst case? Kitty surgery (cha-ching!) to take that thing out. Hopefully it won't come to that.
