I know that rats should get at least an hour of free-ranging every day, if not more. But does that mean the rat has to want it? My rat, Remy, will come out of the cage for half an hour or so, run around and explore and stuff, but the he'll suddenly decide that he wants to get back to his home and will do whatever it takes to get back to it. This might be a sign of boredom with his free-range room, but even with cardboard castles, mazes, exc. he still wants to go back in before the hour is up. Should I force him to stay out, or what??? And advice would be greatly appreciated.
