It looks like a gloomy day outside so Mia and Dukee might just be feeling lazy today. Just like us humans, cats can have moods like that too. A cloudy day might make them feel content and sleepy which leads them to a day of leisure. And when it comes to nap time, they might lay anywhere.
A warm leather stool because the sun came out.
Or a comfy bean bag stool near Mom.
As long as Dukee and Mia are comfy and happy is all that matters. How are you going to spend your Sunday?
