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. 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).
Veterinarians often come across such cases, and many of them will work out an arrangement for people who want to help the animal. However, make sure you tell the veterinarian the situation before he or she examines and treats the pet.
If you find a stray, you should also ask the veterinarian to check for a microchip to determine whether the animal already has an owner.
If you are unable to keep, or maintain an animal you should contact your local Humane Society, or Animal Shelter.
