I just played in my world from version 1.16.4 to 1.18 pre-release 6, and when I tamed the cat, I certainly didn't let him go anywhere and he sat when I wanted to play version 1.17.1 he didn't get up and I don't know what to do and so they don't want to get up with other mobs either. I'm playing pre-release 6 now
 
I just played on version 1.16.4 and up to 1.18 pre-release 6 and now my tamed one didn't want to just get up
 

 
1. first you need to play version 1.16.4 and up to 1.18 pre-release 6 2.then you need to tame a dog or cat and give the command to sit and leave them in this position, presumably for 324 days of playing time 3.go from version 1.16.4 to 1.18 pre-release 6 and it will work
