This is Blue, she is the quietist and yet has turned out to be the most adventurous of the Blue Team. This is part of their Christmas present it was meant for them to share, but the others treated it as if it was poisonous and Blue got at it first, as a result she 'thinks' it is hers and will have a go at the others if they try to play with it. Mind you the same is true of the swing so the others play with this when she is on the swing. Ahh cage politics don't you just love them.
It is a great foot toy, Minty is best with his feet and will hold it still with one foot while he tries to remove the rings. Blue just grabs it as throws it around. Bless.
