Our pets like to soak up the sun and in the early afternoon, the stairs get a lot of sun. That is where we found them enjoying the sun when we got back from grocery shopping.
Buster (orange) likes to greet us at the door like a dog, but Emma (gray tuxie) would feign indifference.
While Buster went one step lower, Emma remained in the upper landing/rung to continue soaking up the sun.
The reason why Buster went one rung lower? To give catpapa a high five or high four for getting his favorite noms.
