As long as basic cleanliness guidelines are followed there is NO problem having both!!!! I wouldn't hold one on my lap while having the other on my shoulder LOL or put them in the same cage but as long as you wash your hands in between handling there is no problem. Yes they can carry salmonella but in all the iguanas we have rehomed/housed we have only had three test positive. We have actually had MANY more aquatic turtles that carried salmonella (and we have had much less of them in!)
