Floor time, we get there cat toys out. They have a cube like this,

but that actually fits in there cage so it's sometimes in there too.
But they also have a kitten play tunnel, which is like 3 tunnels which come together, far to big for there cage,

(like this but in different colours) but they love running around in them, we put the cube at the end of one tunnel and there cat bed at the end of another, then one is left open where we sit.
I've been teaching them tricks and things atm, Chester has now learn't his name and comes to you when you call both in and out of the cage. Bentley is learning to go up on his back legs on command even when there's no food around. Marmite... well he's not so co-operative.
Marmite, is a much less lively piggy as he lives alone, he likes nothing more than getting in my mums dressing gown and just snuggling up wherever he can.
