How much does a hippopotamus cost (retail)?

Around $100,000. Seriously, they are not cheap. They are very expensive and very rare. Most zoos do not even have them. By the way, they are illegal as pets. You would have to obtain all of the zoo permits and actually OWN a zoo. For good reason if you ask me! They are not pets you can just keep in your backyard. You would need a giant enclosure and years of research and experience before you could get one.

I have no idea how much the cost but a hippopotamus is not a pet. They belong in their natural environment. They can be dangerous.

Hippos are too dangerous, I would settle for an elephant instead, besides they are much friendlier and will play with you. I would adopt one from a shelter for abandoned or abused circus animals. We have such a place near Sacramento, Ca. If you are lucky enough to live near a shelter they can keep it for you and you can visit and help out on a regular basis. The other animals there will love your company as well. Watch out for the giraffes they will try to eat your hair, or lick your neck. Pretty scary.
