Sure Laptops are nice and warm, but I suspect the real reason that kittehs love to lay on them is that we stop whatever we are doing to take a photo of just how cute they are. I first posted this on BuzzFeed as Kittehs Using Laptops Correctly in a response to Puppies Using Laptops Incorrectly.
This is my kitteh, Laguna. She
hopped onto my husband's laptop when
he left for a minute.
