I recently bought an NX pet through the NX that I've acquired by voting. However, I've found a pet on Donor section of the shop that I really like and wanted to ask if there is a way to get rid of your pet? I love my pet but unfortunately I think I'll have to give him away... Please don't report to PETA.
If it helps, you can have multiple pets at once. There are slots for three of them in your info panel, and you can switch between them by double-clicking in the cash tab of your inventory.
You can't have multiple pets as the skill for that is currently disabled. In the new source you will be able to have multiple pets and you can transfer pets within the same account using the cash shop inventory.
