The written contract that we enter into with our adopters says that you agree not to abandon, give away, sell or dispose of the pet in any way and to notify us immediately at any time you determine that you no longer want it, or no longer can keep the pet, so that we can take the pet back to arrange for another adoption. You agree to give us adequate time to find a suitable temporary home for the pet and to protect the pet from harm or neglect during this time interval.

In plain English: You may return the pet you adopted from us, at any time, for any reason, but contact us to arrange the return, and please allow us time to make arrangements for the pet.  

If the pet is returned within two weeks of the adoption, you will get a full refund.  No refund is given after two weeks.
