I do not currently have any retired mommies available.  When I do if there are any quirks or eccentricities, they will be disclosed and discussed with you in depth before I decide whether your home is a suitable placement for each individual or not.  That being said, there are no refunds on retired adults.  However, if things don't work out, I will take them back as long as they have been properly vetted (with documents from your vet) and all of the paperwork sent with them is included in their return.
