Maybe include as little information as possible to make them question whether or not the cats are part of an exhibit.

You're so smart, Bio.
I'll hire you as my marketing consultant or whatever's the fanciest name.

Can we have an installation where the members of the musical Cats are locked in a glass box while in their costumes? The actual cats can look on.

Would visit that exhibition.

Cats watching cats?? So meta. Perfect.

Thanks DbM, I'll be sure to have one in Austria

If it's a traveling exhibit we need to make sure we ration the cast members. I'm not sure how long they will last locked up without food and water.

wait
I'm ok with not paying them, but no food and water? THERE'LL BE CATS THERE

The human cats won't get any. The actual cats will.

oh
ok that sounds much better

Yeah, I'm not THAT evil. I'm only interested in human suffering.

we can call that an art installation too
how long can an actor suffer for art

Didn't Marina Abramovic do that in a sense? And Shia LaBeouf.

hers was painful to see D:

She's probably a robot in disguise.

She'll be one of the leaders of the robot takeover?

Yeah, her specialty is staring at people to make them uncomfortable enough to just leave.
