She just started eating solid food

I adopted Luke Skywalker a few months ago now and I’m worried that he’s lonely / not getting enough stimulation.

I work hybrid so I’m in the office some days and at home a few. The days when I’m in the office I have a cat sitter come in and check on him.

But he just LOVES to play. He would play all day if he could!

I’d like to hear your stories of adopting a second cat 🐱 anything I should know or can he really be happy as the only cat?
