I have one of those dog pee pads that I put under the litter box on top of the plywood. It helps keep any dingles or pee misses (I have genius cats) from getting on the wood.

Finally, a comm for that one user who hand-makes longbows. This ones for you, comrade.
I bet something like a hardwood floor finish might be a good place to start looking
That shit got expensive as hell, wtf
Maybe brush on a two part epoxy?
Yeah, I think this is the way to go. Or like rubberizing paint or something. Whatever is cheapest.
Cool thanks for suggestions
oil-based polyurethane (especially high-build) is pretty serious with just a few coats, but isn't available in all parts of the country due to the VOCs given off during the curing phase. sanding between coats forms a great bond. i'd use an old tshirt or some lint free rag to apply and a little tiny can from a generic hardware store would be more than enough. it takes like 1-2 weeks to fully cure and become scratch resistant. there's videos and plenty of resources online for how to apply it. it's chill, just takes a lot of waiting between coats / overall. it can really make wood look slick and bring out the beauty of grain patterns.
water based is lower VOC but i don't think it would stand up to the piss.
Perfect thanks will check it out
Wear a mask and apply it and let it cure somewhere covered but with very high airflow, like outside under a covered porch. Some people are really cavalier with the VOCs, but they can absolutely mess you up.
Just to add on to this: let it cure completely! Those VOCs may be just below perceptible to you, but that little kitty is way more sensitive to the harmful effects
Oh absolutely. Way safer to overestimate the cure time than underestimate and hurt Kitty.
I found that diluting oil poly with mineral spirits made applying it smoothly easier. I started 50/50 then either increased or decreased the amount of poly on subsequent layers. I think increased. And use plain mineral spirits to remove dust after sanding between coats.
What part of the box is the cat going to pee on? Aiming error and they get the walls? I assume it'll be on the inside?
In that case it wouldn't matter how it looks so just keep an eye on the trash for an impermeable sheet material you can fix on the inside. Plexiglass would be perfect but see what the universe sends to you. Or you could buy something low cost like laminate flooring... go to a big hardware store and look around they have many different waterproof materials. Unless you really enjoy the process, or what to learn it for another project, I think doing some expensive elaborate wood finishing would be a waste. If you have already built it, it'll be a pain in the ass to now finish the inside smoothly.
To be honest they shouldn't pee on it at all as the tray itself is massive, maybe piss mist would rise and touch the ceiling of the box?
That's a really good suggestion though thank you, definitely sounds like a good option for me
