When you buy a ferret at Petco do have to sign any papers?

I do not have access to real-time information, including specific policies of pet stores like Petco. Therefore, I cannot say for sure whether you need to sign any papers when buying a ferret at Petco.

However, it is highly likely that you will need to sign some paperwork. Pet stores generally have forms related to:

* Purchase agreement: Outlining terms of sale, care instructions, and potential health guarantees.

* Health certificate: Confirming the ferret's health status.

* Adoption agreement: If the ferret is from a rescue or shelter.

The best way to know for sure is to contact your local Petco store directly and ask about their adoption procedures.
