The answer to your question may vary depending on your location, as different countries and states have different laws and regulations regarding pet ownership. Some commonly owned pets that are legal in many places include dogs, cats, fish, birds (such as parrots and canaries), rabbits, hamsters, guinea pigs, and reptiles (such as snakes and lizards). However, it's always best to check with your local authorities or animal control to confirm which animals are legal to own as pets in your area.
