He's had no reaction so far and it's about 2 hours later. I googled and found an item similar about the possibility of pancreatitis and another that said if it's not a large amount, it's probably okay. I'll keep an eye on him and if he shows any signs of distress, it's off to the vets. Just like having a toddler the way you're going along okay and then suddenly they've got into something worrying.
