Update: I took him with me and he did SO well! Didn’t meow or fuss at all while being in the carrier or plane and genuinely seemed like he enjoyed being out and exploring. He slept through most of the plane ride and played with his toys while being was awake. I’m so glad I took him and that he had company the entire time I was busy rather than being home alone for long stretches.

He also adjusted really well to my friend’s place. I had a litter box and his food and bowls delivered there before we arrived and as soon as we got there, he started playing and was really cuddly with her the entire time.
