Even non scened litter is usually scented. I know it can be hard on
asthmatics. Candles and air fresheners too. Maybe the corn based stuff?

That's a good thing to know. I don't like heavily scented litter anyway. Just
think how it smells to a cat, their sense of smell is so much more acute than
ours is.

Purrs for you, Frank & Nikki. I'm glad they're feeling better.

We used to buy a brand of litter called Ever Clean, that used to be very
good, although a bit expensive. One day they changed formulas and the
antibacterial formula that we used starting having a scent! I called the
company and got a refund, but no explanation as to why they were doing
that. We now use another litter that is not scented, very little dust,
it has activated charcoal and it's way cheaper! :)

The litter I've been happiest with is "Swheat Scoop"

which is made from naturally processed wheat.  It clumps well, has a natural
deodorizing ability (which is effective even with my sister's four cats) and
is 100% biodegradable.  I also don't worry about them ingesting any of it.
It does have some dust but not nearly as much as any other litter I've
tried.  The only concern I would have is obviously if a pet had a wheat
allergy.  NAYY :)

My Simon isn't asthmatic but he sneezes a lot and has done so for years,
just like me. I recently bought two of the Oreck XL air purifiers and since
then both he and I sneeze a LOT less. Maybe some sort of air purifier might
help your kitties?

I remember a week when both Joel and I were uttelry sure we'd come down with
the world's worst headcold - sneezing, asthma, no energy etc etc etc.

WE eventually figured out it was the plug-in air "cleaner" that I'd
installed in the laundrey to deal with the cat box smell. Apprantly it was
supposed to neutralise odour and disinfect germs rather than just mask the
smell with perfume. I'd disagree with that, but even if it was correct, I'd
prefer to smell the litter box than to feel like that again. And it wasn't
an odour I was particularly fond of either.

The only perfumes I really like are simple ones based on natural oils, and
while I"m not badly allergic, I find many artifiial sents overpowering and
nauseating. Joel is allergic to most laundry detergent and such if they are
perfumed, can't stand the perfume counters at big department stores, and
can't even walk into what I call "hippy shops" that have inscense burning
without gasping for breath. So it always seems to be the way when we go to
the movies or have to sit somewhere for a period of time that the person who
sits next to us invariably has drowned themselves in a bottle of very cheap
perfume or aftershave.

My "perfume", if I wear any at all, is just a mix of essential oils in an
almond oil base. It it subtle but has a warm pleasantantness about it - like
a warm summer evening - and has yet to make either of us gag. Best of all,
its far cheaper than most of the brand-name perfumes.
