Marley's Quest for Cats

It is no surprise that Marley is obsessed with the cats when she is over here. We use gates to maximize the choices the cats have and they are often quite bold (or stupid) when making those choices. Marley just watches them and wonders how she can get closer to them. I am not even sure of her motives, i think it is pure curiosity. What would she do if she "got" one?
