I know you've probably said something about this idea in the past, i just cant find anything.

What if you added small pets? such as snakes, spiders (would need a special setting to toggle those off because some people are scared of them), guinea pigs, hamsters, ect. they would function like other items with animals, the animal would have a hidey h***, and frequently come out and wander, if you wanted to go the extra mile you could add feeding them, taking them out and playing with them, ect.
