was it an allergic reaction

I feed everyone the same food: Iams ocean/rice dry formula. The bengals have their own bedroom w/ 2 bowls (free-feeding.) Cinnamon & Fluffy have the same. I bought some of the Iams hairball control food (but it's also a weight control for cats 1+ yrs. and over) and I've been mixing it into Fluffy & Cinnamon's bowl til I can switch them over completely. Anyways, the 2 boys think it's their food. I've noticed Scooter seems to be having big sneezes. Could it be from the food? He seems to only do this after he has eaten it. He doesnt have any run eyes, or anything. Anways, I guess if they come in, I will have to put Fluffy & Cinnamon's bowls up. Either way, Scooter's vet checkup is due, so I will ask too.

IMO I don't think it's the food. I would lean more twards an inhaled allergy and the food switching may have just been a coincidence.
