We have a dilemma here.
If we hire catboys, they may understand the concept of money. Cece might have to pay the catboys.
We can convert the catboys to catbots (that greatly resemble catboys), to avoid paying them wages, but we may also upset Vivy, one of the possible lounge singers. Usually Vivy is employed and lives in the Nialand theme park, and receives no wages, but she might be an independent contractor in this case, and could want wages. GLaDOS would want wages to continue experimentation at Aperture science.
If the catbots are equally as smart as Vivy or GLaDOS, we may have a sentient robot rights issue, if some robots are being paid, and others aren't. If we make them too stupid, that may cause issues in their service.
I guess we could give the catbots the same deal as Vivy had while she lived in NiaLand, and house them somewhere in the cafe or have a catbot shed/garage for them. I don't think GLaDOS gets paid by Aperture science either. Sentient robots being housed by their workplace don't usually receive wages.
