Most humane organizations do not have the space or funds to care for your pet indefinitely and cannot guarantee that someone will adopt your animal, although some may be able to board and care for your pet temporarily until he can be transferred to his designated caregiver. There are, however, a few organizations that specialize in long-term care of pets of deceased owners. For a fee or donation, these "pet retirement homes" or "sanctuaries" may agree to find your pet a new home or care for your pet until she dies. Be aware, however, that pets are companion animals who need lots of care and affection; they may suffer from long-term confinement in such facilities. Your pet will not want to be institutionalized any more than you would want to be.

Before making any formal arrangements, visit the organization to see how animals are cared for, where they are confined, who looks after them, when they are socialized and exercised, and what policies and procedures exist regarding care at the facility and placement with a new family. Also consider what might happen to your pet if the organization were to suffer funding or staff shortages. If you decide to entrust the care of your pet to an organization, choose a well-established organization that has a good record of finding responsible homes quickly.
