In Old Lady's Java World (originally 'Brave New World') my cat has repeatedly teleported to follow me great distances, even when I make her sit.  For example, she went from home base 212 67 -165 to (stronghold) 1196 -8 1180. When I teleported back to base she didn't follow me back, and the 'teleport entity' commands I've found online don't seem to work on her. I tried to see if she would follow me through the End Portal so we could go back to base via the End exit, but she wouldn't follow. I ended up having her follow me as I walked back to base through the Overworld.

I don't have any other pets but the cat in Old Lady's Java World. In my current Bedrock/Switch and Bedrock/PC worlds making the pets sit before I teleport does seem to work and they haven't been following.

Any help would be appreciation - oh, and have a happy holiday!
