This was not a tired kitty in the slightest! He went exploring around the apartment while the dogs were out on their walk. Gobbled his breakfast right now and figured out how to get up on the side table so he could look out the window. Then he went and hung out on the bed while I got ready for work, where Sawyer was just staring at him. I went in to grab my shoes and he started to crouch behind the pillows, so I grabbed my phone and caught the above shot.
Sawyer is being a little bit of a pest about his excitement, so Kitty has hissed a few times at him. Nothing big and no claws, just a gentle pushing with those little feet to get Sawyer's face out of his.
I have put him in his litter box a number of times but he hasn't done anything except maybe pee. It's hard to tell with these paper pellets.
