LOL! Nikki used to deliberately leave her tail sticking out from boxes,
bags, under the covers, etc, wherever she was lurking. That tail had a
life of its own!

Clifford (RB) clearly would play hide-and-seek, but part of his assumptions
about the rules were that tails were invisible and could not be used as
clues to the cat. One must understand that he was coal-black except for the
last inch of his tail, which was snow white; it took a couple of years of
growing up before he accepted that the white spot was not an evil being
chasing him.

As far as I can tell, however, he had studied tail-smashing with an
alligator. In his prime, he was 16 pounds, with muscles rippling under his
not-very-loose skin.

One of my indulgences is a bubble bath. Clifford, once he grew up, was a
very intelligent cat, except when his tail was involved. He would keep me
company in the bathroom, but, when there was bubble bath in the tub and he
couldn't see the water, he'd happily climb on my chest. Unfortunately, he'd
lash his tail while doing this, getting it soaked, such that it became
something of a club. Given the proximity  of a large wet tail to tender
parts of mine, I'd have to keep wringing it out while he purred.
