My kitty stinks! So I have tried adding the baking soda to the litter. Seems to help some. I'm thinking that maybe it is the antibiotics my kitty in on - she is off now so I'm waiting to see - smell! YUK! I do used Fresh step Cedar (first box) and will try the regular Fresh Step next time. I also have the clay litter mixed in as she likes to dig and bury her stuff and it seems like good filler instead of all Fresh Step (very expensive!). Also the clay doesnt' track so bad and seems to help. Debbie
