Yes, the dish, not the treats in it (well he ate those too, but a while ago.)  

We give Porky treats (freeze dried raspberries or strawberries and such) in small silicone baking dishes.  They are nice small dishes for small amounts of treats.  he likes to toss them around after he eats, so I have just let him keep them in his room after eating.  he has had regular access to them for months and always just tossed them after eating an treats in them.   I don’t know what made him suddenly decide to chew apart this one.

I’m not sure how much he may have actually ingested.  There is a lot of the bowl chewed off, but there are also a lot of chewed up bowl pieces strewn about.  They are too chewed up to reconstruct the bowl and figure out how much is actually in Porky’s belly.

Should I take him to the vet in the morning?  Should I just ignor it as long as he poops well?  Do I need to spend the whole day checking his litter box?  What are the chances of a blockage?
