Stretch, stretch, stretch! Eventually you will become so long that your front and back paws will touch opposite sides of the futon mattress, so long as you don’t eat the mattress first.
Don’t worry if you’re not as tall as your big brother. You can lengthen yourself daily through a targeted stretching routine.
Go ahead and flop on your back and stretch your supple spine out to its fullest extent from front paws to tail tip during an important conversation. If your interlocutor is a cat, he’ll understand.
If he’s not a cat, why were you talking to him in the first place?
