Rabbit & dog urine on skirting boards: what works

Urine on wooden skirting boards from multiple animals is one of the trickier situations — the uric acid soaks into the paint or bare wood and just keeps off-gassing, which is exactly why your rabbits and dog keep returning to the same spots. The only thing that actually destroys urine odour permanently is an enzyme-based cleaner; sprays, bleach, and scented products just mask it, and animals can still smell what's underneath. Before I point you to the right product: is this set-in over time or are you catching it relatively fresh, and are the skirting boards painted, varnished, or bare wood?

Good to know — painted gloss is actually helpful because the urine mostly sits on the surface rather than deep in the grain. Set-in still needs a proper soak time to work though. Tell me a bit about the Cavalier: is he neutered, and is he actively marking on the skirting boards or is this mainly the rabbits?

That tracks — unneutered or even just territorial rabbits will mark vertical surfaces repeatedly, and once a dog detects it, he'll feel compelled to add his own message. The key issue is that you need to neutralise the whole length of those boards thoroughly enough that neither species can smell residual scent anymore, otherwise the behaviour just continues regardless of how clean it looks. For this I'd go with Bio-One Odour Eliminator & Stain Remover. It's a professional-grade enzyme formula that's safe on painted surfaces, non-toxic once dry, and specifically effective on the uric acid compounds that make rabbit and dog urine so persistent. Spray it on, leave it wet for at least 10 minutes — longer on anything that's been building up — then blot and allow to air dry fully. Don't rinse it off; you want the enzymes to keep working as the moisture evaporates.

Sections are fine — in fact it's easier to work that way so you can give each area proper dwell time without it drying out before you're done. Start with the corners and the spots you know get hit most, since those are where concentration will be highest. One practical tip: once the boards are fully dry after treatment, run your hand along them. If you can still detect anything faintly, do a second pass. With months of buildup it sometimes takes two applications. After that, the rabbits losing the scent cue makes a real difference to how often they re-mark the same spots.

I'd move the rabbits out while you're applying it and for the drying period — not because Bio-One is particularly harsh, but rabbits have sensitive respiratory systems and you don't want them hopping through it while it's wet. Once it's completely dry it's fine. Same goes for the Cavalier. Give it an hour or two with good ventilation, and you're good to let everyone back in.
