litter allergy

3 year old ragdoll male -i usually use the arm and hammer litter and i tried a different litter yesterday and i think its dusty. my guy chowder started sneezing right after using the new litter i know its this. i’m switching his litter today but i am just curious i did some research, and learned that silica litter may be good to try? should i try unscented silica or go back to arm and hammer? thank you!
