How to force-own Minecraft cats?

I've been having a little bit of a problem with my Minecraft cats.
I've tamed them for a long long time and now I used another launcher, because the one I was using was glitching, and I tamed another cat, after using that new launcher.
Now I can only command my new cat to stand or sit, but the other ones don't seem to recognize me.

Is there anyway to make my cats be owned by me through the new launcher, like "force own" them?
I assume I have to use commands, but since it won't give me any game advantage, I don't consider it cheating.

Solution 1:

This can be done my merging your UUID into the cat's OwnerUUID NBT tag. This command should allow you to do that.

/execute as @e[type=minecraft:cat,distance=..10] run data merge entity @s {OwnerUUID:"yourUUID"}

You can check your UUID on https://mcuuid.net/.
