Does your friend have an open spot in order to accept the pet?

There shouldn't be anything special? o_o

Is the pet showing up in search? Like, did someone else get it or is it just gone?

That's weird :S Does the pet show up if you go to it's profile? What owner does it say (www.subeta.net/pets/petnamehere)

If its not on your account or her account I suggest filing a ticket.

-cake, Maybe it will be worth sending a ticket about? Or telling the person who has it about what happened? :x

Try contacting the person who got it instead and explaining what happened. I'm sure they're wondering where this pet suddenly came from. They'll probably be able to send it to the right person.

In that case, I would file a ticket and see if the staff can get the pet sent to the right person.
