Finally looked it up (we were out of town for a night), and Fred the Insane was one year old last month. He’s at the foot of the bed looking innocent.
Ack, a year old and still in “Hey I’m a kitten, OH! STRINGGG!” mode.
He may slow it up a bit in a couple more months.
Or he could descend even further into feline insanity.
Which actually would be endearing after a fashion as long as he doesn’t try actively to destroy people.
