My wife also ordered a CATLINK Pro-X self-cleaning litter box
Good choice on the a CATLINK Pro-X self-cleaning litter box, we will pretend it was yours. :) 15 days is easy to achieve if you switch to crystal sand, or some other non clumping type for the period you are away. The 13L dirt capacity is not that important because if 13 lt of bentonite mixed waste is in the waste bin, no sand will be left inside the litter box, it will be empty, they will have no place to go. For 15 days you do not need just a huge waste bin, you also need a way for the the litter box to auto refill, or not loose too much sand. Crystal sand helps a lot on that part.
You mentioned in the Greek forum that polyurethane resin is cheaper than epoxy and has a more plastic-like feel, whereas epoxy is closer to polycarbonate. Does polyurethane feel similar to ABS, or is it softer? Also, is it stiff enough to support a cat’s weight (assuming the design is similar to your tank as example)?
You are right, you can use polyurethane resin too, it is not as penetrative, you will have to use the brush running along the edge technique a bit more, the end result is indeed ABS like. Not soft, just bendable a bit, but strong enough. Price wise the difference it small, If you have one or the other use what you have to test, but if you get one I think an epoxy resin like the clear-21 is best, the polyurethane will need extra care to store what is left once you open the can.

Thank you so much for all these details! My wife also ordered a CATLINK Pro-X self-cleaning litter box—apparently, she doesn’t have much faith in my DIY skills. 😅
That said, this could be a great opportunity for me to draw some inspiration from it.
Our main concern has been how long we can leave our cats alone. We were aiming for around 15 days, which really limits the available options on the market. This litter box has a 13L dirt capacity, which might work for us since our cats (and their poo) aren’t too big. However, I wouldn’t want to rely on it long-term.
One feature I found interesting is the microwave radar sensor, which eliminates blind spots. It seems like a great idea to incorporate into a DIY project.
I didn’t purchase their entrance step, though, because $99 for a piece of plastic feels excessive. Instead, it seems like a perfect opportunity to test your cardboard-resin method.

I’m really looking forward to more details from you. Thanks again for your help!
