Hi there!
That would depend on where the cat is?
Is the cat lost? If so, you will need to file a support ticket with the cat's ID# from the online pedigree page and our team will get the kitty back to you. You can read more about filing a support ticket here:

Is the cat in the online cattery? If so, then you will need to retrieve it using a Cattery Dock. You can get the dock here:

I hope this information helps, if you have any further questions or any issues, please feel free to contact me in world
