Legally, once you decide to adopt or “take in” an animal, you become the owner. As the owner, you are responsible for the pet’s care. When you take in a stray, he or she may be injured and require veterinary care. Because the amount you pay for his or her care isn’t related to how you’ve acquired the pet, you need to carefully consider whether adopting a stray pet is a financially advisable decision. If you can’t afford the pet’s care, you have the option to relinquish the animal to a local humane society or shelter (although some shelters cannot guarantee that the pet will not be euthanized).
