Every now and then (when we get icy, snowy, blowy weather here in Texas), our cat gets on our bed, and we turn the electric blanket up to high. At first, she's all curled up in a tight "I'm cold" ball, but about 10 minutes later, she's stretched out like she's sunbathing in the heat of summer. That's when you know your kitty's done, and you can turn your electric blanket down or off.
She also does a great rendition of "Hello"--usually when it's raining and she's stranded and desperate on the window sill!!
Thanks for sharing the poem.
