Another fun thing about boxes is waiting for Myst or Dandelion to come by and jump in. Then I can crouch low and paw at them until they jump out to chase me.
Humans can be fun, too. One time Terry was playing tag with me and I ran up the hall. I stopped and looked every which way. I thought it would be very clever to hide in this box, so I jumped in and crouched low. I figured she could not find me at all. I never understood how she could just pick me up so easily. I was sure I was well hidden! Sometimes humans can surprise you with their cleverness.
