This reminds me of a friend of mine. When they were getting their first baby (human ) he said: We will be very relaxed about it. You just have to consider it all as normal. And when he is 4 he can already help doing the dishes.

Ok, when the boy was 4 we sat in their huge kitchen enjoying a dinner while the boy, Samuel, was playing drums with all the pot covers in the kitchen

I am sure your cats just had fun with the laundry
