I've had a few good recommendations on here but am I right in thinking for example that clumping litter helps mainly with urine smells? We don't have a problem with stinky wee, just poo. (We scoop as soon as it's done and use a tray with lid and door, but would prefer less smell if possible, especially for when we are out and have a babysitter for example!) Would a change of litter help?
(Please don't suggest moving the litter box - trust me, I would not have it in the living room if we had anywhere else it could live!)
