You can actually get real "jumbo" type rats. They have a more technical name that's on the tip of my tongue...Well, they usually come with health problems like diabetes and don't live very long, so most breeders discourage breeding them. I don't believe you can find one in a pet store.
Are you thinking of the Gambian Pouched Rat maybe!? Otherwise Luckies is right about your statement.
