What Litter is good for a Cat with Asthma?

[mews2much]

My 16 year old Cat has Asthma and I am using Yesterdays Mews.
She also has a Bladder Infection again.
What litter is good for a Cat with those problems.
I have tried some other litters and her Asthma acted up.

I would think a dust-free litter. I really can't answer this because it's more of a medical question and I'm not a vet.
