Litter Odor Control With a Dog in the House

A Frenchie and a senior cat sharing the same space — litter smell becomes a real issue fast, especially because dogs tend to sniff out the tray like it's a snack bar. How long have they been living together, and where do you keep the litter box right now?

That makes total sense — when a senior cat loses mobility, the box has to come to them, which usually means it ends up somewhere central and visible. So the challenge is neutralising odour quickly enough that it doesn't linger in the main living space. Is your cat on a standard clay litter at the moment, or something else?

Completely the right instinct — older cats can get very unsettled by litter changes, so I wouldn't touch that either. What I'd change is the litter itself, not the box or the routine. My recommendation is Arm & Hammer Clump & Seal cat litter. It uses baking soda activated by moisture, so the moment your cat uses the tray it starts neutralising ammonia odour rather than just masking it. It clumps tightly too, which means less mess and faster scooping — and less opportunity for the Frenchie to go investigating.

Fair concern, and it's a real difference with this one — the odour neutralisation comes from the baking soda chemistry rather than fragrance layered on top. There is a very light scent in some versions, but it's subtle. If you want to be safe, go for the unscented variant specifically. For a living room setup with a dog who's nose-first into everything, it's the most practical solution I'd point you to without changing anything about your cat's existing routine.

Good call. Give it a week and you should notice a real difference. One extra tip: scoop once a day minimum — the clumping does a lot of work but frequency still matters when the box is in a shared living space. Your cat will appreciate it too, senior cats can get fussy about a box that isn't fresh.
