Over the years, I've had a number of cats, and I've noticed that they all have their own preferences for how they prefer their toys to behave. Some of them wanted their toys dragged on the ground, some of them were only interested if they were fluttering in the air, and our current cat doesn't care, so long as she can pounce on it from hiding. I've always presumed that this corresponds to different hunting behavior in wild cats - a preference for catching small ground critters, birds, or whatever they can sneak up on.
Now I'm wondering what determines this preference. Is it genetic? Taught? Or just subject to each cat's individual preferences? Or is it simply me reading too much into how indoor cats play with human-powered toys?
