The pellets are excellent for absorbing odours and you only need a small amount in the litter tray. I've switched to the pellets and can't believe how the smell of cat urine has disappeared!
You can buy a forty pound bag of pellets for less than $5 and it will last a one-cat household about three months. A hardware store salesperson recently told me that 60% of wood pellets sold are for actual wood stoves, and the other 40% are purchased by cat owners!
PROS
Cheap!
More natural
Odour-absorbing
No more kitty litter trail across your floors
CONS
Seasonal item
Must clean litter frequently (the poop, especially)
You can mix the pellets with a bit of regular litter to ease them into it. I didn't do this though...I just switched over to the pellets on a Sunday and watched my kitty like a hawk to ensure she used the litter box as per usual.
