One of our current four cats is now around 8-10 (ish) years old - cannot be exact because he was a stray originally. He still scoots around playfully with the others. Previous cats have been the same... although there are always exceptions, either due to temperament, or health.
Boxes seem to be a much-favoured "prize" that they all have in common. If the Postie delivers a parcel, the moggies appear as if by magic, to see who can lay first claim to the box. Great fun to watch them
