What do cats dream about?

[kedrys]

I'm sitting here reading the news, and Evie's asleep on the desk is having a great big dream, with the twitching poosies and whiskers and everything. I always wonder what it is they dream about, wonder if I'm ever in their dreams the way they're in mine, and suspecting it's more complex than chasing big fat juicy squirrels (which none of my cats has actually ever done in real life).
