First, decide whether you want all your pets to go to one person, or whether different pets should go to different people. If possible, keep pets who have bonded with one another together. When selecting caregivers, consider partners, adult children, parents, brothers, sisters, and friends who have met your pet and have successfully cared for pets themselves. Also name alternate caregivers in case your first choice becomes unable or unwilling to take your pet. Be sure to discuss your expectations with potential caregivers so they understand the large responsibility of caring for your pet. Remember, the new owner will have full discretion over the animal's care—including veterinary treatment and euthanasia—so make sure you choose a person you trust implicitly and who will do what is in the best interest of your pet.
Stay in touch with the designated caregivers and alternates. Over time, people's circumstances and priorities change, and you want to make sure that the arrangements you have made continue to hold from the designated caregivers' vantage points. If all else fails, it is also possible to direct your executor or personal representative, in your will, to place the animal with another individual or family (that is, in a noninstitutionalized setting). Finding a satisfactory new home can take several weeks of searching, so again, it is important to line up temporary care.
You also have to know and trust your executor and provide useful, but not unrealistically confining, instructions in your will. You should also authorize your executor to expend funds from your estate for the temporary care of your pet as well as for the costs of looking for a new home and transporting the animal to it. The will should also grant broad discretion to your executor in making decisions about the animal and in expending estate funds on the animal's behalf.
