I'm sure it has some developmental link, does anyone know what it is? Just curious .
No idea, but i guess they all just get to a stage where they work out that when something is out of view, it isn't necessarily gone - just hiding. Isn't it funny when they try to hide huge things under small things. I guess it takes longer to learn how to understand sizes.

Not sure what it means when your cat does it though marcellus

Keep the remote out of reach though. It can be a real pain when that gets hidden
