<p>Where was he when you got home to find this? I know one of my cats would have been sleeping in the back of the closet after a major noise like that; another would not care a bit. If your cat was showing signs of alarm, it’s unlikely he ate anything.</p>
<p>Did you look at the dry food before you threw it out? Did it look like it was undisturbed after the glass landed on it? Were there pieces on top of the rest? If so, probably untouched.</p>
<p>I’d watch the feces for blood and also watch for any abdominal tenderness, which would be a sign of internal bleeding. If he’s licking his belly a lot, that would be a sign that things aren’t normal.</p>
<p>You might want to make an appointment for a “get acquainted” visit with a vet, just so you have someone to call next time. You could take the cat in and get his claws clipped as a way of seeing if you like them. You also might want to figure out if there’s a 24-hour emergency vet you can use. (Here in Portland, we have a 24-hour animal emergency clinic: [DoveLewis</a> | Emergency Animal Hospital | Portland Oregon](<a href=“http://www.dovelewis.org/]DoveLewis”>http://www.dovelewis.org/).)</p>
