Sea Kittens!???! What are sea kittens?

A bit of background: there is a piece on NPR about PETA (People for the Ethical Treatment of Animals). It talks about their new program to save the sea kittens. Sea kitten is the new terminology for fish and the site allows you to dress up fish and hopes that you will think fish are cuter by calling them kittens, so you will eat less fish. Well the story has exploded - with more than 700 comments and counting. Read the story and see the comments here. This is my contribution to the comments (with two very small edits)

I tried to cuddle my Sea Kitten
I put him in my bed,
I wrapped him up in covers,
a pillow for his head.

But suddenly an interruption
all whiskers, tooth and claws.
A sneaky, mean, old land fish
took sweet sea kitten in her mean old jaws.

She ran and hid with sea kitten
as I chased and yelled and cried
But I knew at once that dear sweet sea kitten
had done left me. He had died.

I have many memories
of our playful time together.
Our bicycle rides, our scrabble games
Drinking cocoa in bad weather.

I miss my little sea kitten
his flippers and his tail
I have nothing to remember my sea kitten by
but this one small fish scale.
