My 30 second google search has shown that Kangaroo do not need to drink water, as they eat seven times more than a human a day and produce enough metabolic water to sustain themselves, however this could be argued to be a function of organism. This is also something attributed to rodents, as Kangaroo is a rodent. Therefore one could technically argue that by starving it, a Kangaroo will die from dehydration. Technically, one can, not an insect or aquatic animal, die from dehydration without needing h2o to drink.
In order to imitate your previous ableist insult: Holy shit, are you retarded? Like, are you a mentally challenged person> Where in fuck did you read that shit? That's probably the dumbest thing I've read all that month. I don't even dislike you as much as other posters do, I think you've brought up good points, but this is really idiotic.
The only thing I can find on Kangaroos not drinking water is this article (
http://biologicalexceptions.blogspot.com/2012/01/sorry-i-dont-drink.html) which says nothing about kangaroos, it says something about kangaroo rats, which are NOT Marsupials, they are rodents. But you read the name and immediately assumed Kangaroo, which is incredibly retarded. Any child knows that kangaroos are marsupials not rodents. Jesus fuck.
And they don't generate all their water via metabolic bugfuckery. They have a very efficient processing of water, true, but they DO drink water in the form of moisture collection seeds.
And you accuse people of having poor reading comprehension...
