At playtime last night, Kenai managed to pull up a piece of that plastic-ish floss-like thread in carpeting and ate it - it was probably about 2" long. It's about 24 hours later and droppings/appetite/activity are 100% normal, but my concern is that it could just be sitting in his stomach or intestines and could ball up and cause a blockage at some point. Is this a cause for concern, or will it likely pass? Normally I wouldn't hesitate on a trip to the vet, but I'm at my parents' for the holidays for the next 2 weeks, and only trust our vet back down in MA (I'm up in rural NH, about 3 hours away). I was considering looking through all his poo to see if it's passed yet (only a day's worth on paper towels under the grating), but if it's not necessary, it's something I certainly wouldn't mind skipping. Any thoughts or suggestions would be appreciated.
