Some pets are with us for just a few years, while others can become lifelong companions. If you are looking for a pet that will stick around for decades, these ten species are known for their remarkable longevity and enduring companionship.
Macaws

Macaws are large, intelligent parrots that often live 50 to 60 years, with some reaching 80. They require daily social interaction, mental stimulation, and a balanced diet. With proper care, macaws become deeply bonded, lifelong companions for experienced bird owners.
Koi Fish

Koi fish can live 25 to 50 years or even longer in well-maintained outdoor ponds. They thrive in clean water with proper filtration and regular feeding. Some koi have been documented to live more than 100 years in ideal conditions.
Turtles and Tortoises

Turtles and tortoises are among the longest-living pets, with some species like the African spurred tortoise reaching 100 years. They need spacious habitats, UVB lighting, and a specific diet. Owning one is a serious, often lifelong or multigenerational commitment.
Cockatoos

Cockatoos can live 40 to 70 years or more in captivity. These affectionate birds demand lots of attention, interaction, and mental engagement. Without proper stimulation, they can develop behavioral issues, making them best suited for dedicated, long-term pet owners.
Goldfish

With the right care, goldfish can live 10 to 30 years, far beyond their reputation as short-lived starter pets. They need large tanks with clean, filtered water and a varied diet to thrive and reach their full lifespan potential.
Cats

Domestic cats typically live 12 to 20 years, though some surpass 20 with excellent care. Indoor cats often live longer than outdoor ones, benefiting from consistent nutrition, veterinary attention, and protection from environmental dangers and contagious diseases.
Dogs

Dogs generally live 10 to 20 years depending on breed, with smaller breeds tending to live longer. Mixed breeds often outlive purebreds. Good nutrition, regular exercise, and routine veterinary care all contribute to a longer, healthier canine life.
African Grey Parrots

African Grey Parrots are famous for their intelligence and long lifespans, often reaching 40 to 60 years. They require plenty of mental enrichment, human interaction, and a varied diet. Their long-term care needs make them a serious responsibility.
Horses

Horses can live 25 to 35 years, and some reach their 40s with excellent care. Regular dental checkups, exercise, hoof maintenance, and quality nutrition are essential. These majestic animals are long-term companions that require significant time and resources.
Ball Pythons

Ball pythons are popular pet snakes that can live 20 to 40 years in captivity. They are low-maintenance reptiles but still need appropriate enclosure conditions, temperature gradients, and a consistent feeding schedule to remain healthy for decades.
