If you're interested, I once researched painting cats and found a few recommendations, such as mixing some paint with some of the cat's piss to make them wanna play with it. So if y'all wanna try...
...I'm pretty sure I'm making a mistake but here.

Use with caution.
And whatever happens, don't let anyone know I'm the one who gave you info.
I second this decision.
For the question, I'd say be creative. Maybe you can craft a tiny diaper-like thing with a plastic pot and some string, but since y'all drunk it can be hard, so I'd recommend waiting for the cat to start peing, then one of them swiftly lifts it while the other puts a cup under it to collect the precious.
Uh I mean you can also try to paint yourselves but unless you're into some elaborated kinks you don't need pee.
Or if you're set on cat you can ask your local shelter if you can get a cat for a little while and have it pee on a blanket that you can then press to extract the piss.
Also I'm kinda drunk and a bit intrigued tho.
Also demryn's just as drunk but he's So SoBeR hUrR DurR
