Query: Don't buy arm and hammer

As you know cats have their noses in everything, I bought arm and hammer cat litter and found that it had a lot of dust in it. The dust got in my cats lungs and I had to take him to the vet because he couldn't breathe. He was put on antibiotics, He got so bad I thought he was going to die. Both my cats are inside.
