How would you swap the ID? Is that done through name switch? I have two pets that I'd like to swap names and then I have two other pets who I'd like to swap IDs

I'm confused... What exactly do you mean by swapping IDs? What are you wanting to swap exactly?

When you name-swap, you swapping around which name is associated with which ID... Nothing else transfers over.

So for example, if I have an ID of 90876 and another that's 9876564, I can't swap them? Just the name?

No, I'm afraid not. The reason we can change names and name-swap is because the IDs are actually what the site uses for recording things like when a pet was created, what they've eaten, what they've read, even their color and species. So those things stay with the ID and don't get swapped around.

Oh! I didn't know that. I thought it worked like name swapping. Thank you for clarifying :D
