Why are humans always complaining about the weather? Rain is just a beautiful reason to sleep more hours. Instead of 12 naps, I get in 14. When I wake up, I just chase the water drops across the window.
Sunshine is great for rolling around and shining my fur. And a ray of sun is a great place for a nap, all warm and snuggly.
Chasing leaves and snowflakes in the fall and winter are good for keeping in my best buff condition. After all, a primo specimen of felinehood such as myself must keep up his health.
So, when the weather is not to your liking, take my advice and nap until it changes. Yawn.
