I just checked out the information on the Combat website, and this is what is says:
"The active ingredients in Combat products are either fipronil or hydramethylnon. These ingredients are fatal to insects, such as ants and roaches, but have been shown to have a very low toxicity in humans and domestic animals."

I would rinse your cats's mouth out with warm water in case there is any gel left in there. I would monitor your cat to be safe. If you see any signs of vomiting, diarrhea, muscles tremors, convulsions, or lethargy, those can be signs of a reaction to the poison, and then I would take him into the vet immediately. There is no specific antidote, but he may need supportive treatment for his symptoms. You would see a reaction to this ingestion within a couple of hours, so if he's still acting normal by tomorrow, he will be fine.
