I accidentally dropped a q-tip on the floor while Henry was out and he immediately tried to eat it. I got away from him, but he pulled off and swallowed a little bit of cotton from the end. The box says the swabs are 100% cotton, so I'm not too worried that he'll be poisoned or something (but I'm not NOT worried; I don't know what they treat it with), I'm mostly hoping he'll pass it ok. Probably, right? It's fiber, or whatever? Anybody know if it's time to relax or time to call the vet?
