Pre-treat a rescue cat's litter area before they arrive

Pre-treating before your rescue cat arrives is exactly the right instinct — if there's any existing pet scent in that area from previous animals, it can confuse a new cat about where to toilet. The only products that actually eliminate those embedded odours are enzyme-based cleaners. Anything else just masks the smell, and cats have a far more sensitive nose than we do, so they'll still detect it. Before I point you to the right product, a couple of quick questions: is the litter area on carpet, hard flooring, or somewhere else? And do you know whether a previous pet has actually toileted in that spot, or are you treating it as a precaution?

Smart thinking. Dog urine scent on a hard floor can absolutely unsettle a new cat, even when you can't smell anything yourself. For this I'd recommend Simple Solution Extreme Pet Stain and Odour Remover — it's enzyme-based, works on hard floors without leaving residue, and is safe once dry. Spray it generously over the area, let it sit for 10 minutes, then wipe up the excess and let it air dry fully before placing the litter tray. The enzymes break down any urine proteins at a molecular level, so there's nothing lingering to confuse your cat. One bottle will cover that corner easily.

Keep it in the same spot. Consistency really matters with rescue cats, especially in the first few weeks — they're already adjusting to a new environment, and a fixed, predictable litter location helps them settle faster. Once the treated area is fully dry (give it a couple of hours), place the tray exactly where you plan to keep it long-term. The enzymatic treatment removes the old scent, and the litter itself then provides the right smell cue for your cat to understand that spot is for them.

A few practical things make a real difference. Place the tray away from her food and water bowls — cats won't toilet near their food. Keep it somewhere she can approach from more than one direction, so she doesn't feel trapped. Use an unscented clumping litter to start with; rescue cats often come from shelter environments where that's what they know. And resist the urge to move the tray in the first month even if the location feels inconvenient. Once she's settled and reliably using it, you can inch it to a better spot if needed. That's genuinely it — with the surface treated and the setup right, most cats take to a tray without any fuss.
