Round and squishy

These weird, round, squishy things have been tied to one of the chairs I nap on.
They've been there for quite a long time.

















I'm curious about them.
I want to sniff them.
I want to paw them.
I want to claw them.

But whenever my human sees me putting my paws to them, he says 'no, Clive - you'll get a fright'.
Then he moves me onto another chair.

I still don't know what they are.
I want to claw them, to see what happens.
