The crystals are silica gel, which I think is the stuff that comes in packets to keep things like Japanese rice crackers dry. I just remember that the packet always says it shouldn't be opened and the contents are harmful. But if there is no blockage, that rules out silica gel sitting in his digestive tract, absorbing moisture and enlarging itself. So, perhaps the chemical composition has irritated his tract? I'm very glad your vet is going to check out the ingredients. Also, she can call the company (Nestle) and get more information out of them.

I always take in a special blanket if my cats have to stay, though I usually fight against that. Sometimes I've put on a clean sweater for my drive to the vet and then taken it off there to put in the cage.
