Happiness and Contentment and Evolution

Tigger sleeping on her favorite mat in the living room, enjoying the sunlight from our south-facing window, while Norio sleeps mostly under his bench (but still partially visible). This image also shows how well Tigger blends in to busy patterns - most mammals see in grayscale (or mostly grayscale) - for small animals such as cats, it helps to blend in well. So, clearly, Tigger evolved to sleep on busy-patterned mats.
