I'm somewhat of a novice as far as raising meeroos goes, but the sim I've put my meeroos in is a roleplay sim in which the sun never comes. Consequently, all my meeroos do is sleep. I have a parcel on the Linden mainland too, so not having another place to raise them where the day cycles normally or it is always daylight isn't really the issue. The issue is that I want my meeroos specifically to be the roleplay sim and not sleep all the time.

Is it too much to hope for that there could be a way to train your meeroos to be nocturnal?

I don't know if making this available would be as simple as marketing a new nocturnal meeroo home or if it would require having to buy a one-time use vampire-strawberry or something and feeding it to your meeroos, but I would be extremely interested in it.
