"Here, live in this box forever, you get all the food pellets and water you want, but you can never leave and don't get anything entertaining to do" would drive any animal insane. Take a look at animals behaving pathologically in boring zoo enclosures, for example.

A study actually analogous to basic income would have, for example, unlimited generic mouse food and a comfortable home environment, but also have a large exterior environment available to explore, wheels and toys, and a steady supply of puzzles/mazes/etc fitted with tastier treats that the mice could engage with or avoid as they wish.
