Yeah, I have a bed now too.
The kitten’s determination to enter the shoe might be due to its sibling comfortably sleeping in the other one.
Perhaps it wanted to try as well, but the kitten couldn’t get in on the first attempt.
The shoe would either move or the cat couldn’t find the right position to enter.
While it had a frustrating process, the kitten’s sibling was sound asleep all throughout the video.
