figured it was time for a hypothetical...
Scenerio:
A huge 1 km square enclosed cage. no food or plants in the cage, only 1 small watering hole. you put one of every species of mammal you can think of in the cage.

Which animal gets to drink last?

compare fighting/survival styles or use whatever rational for your answer. enjoy the show.

Not sure that I understand the "which will drink LAST" situation but I know who would dominate the pond.

The pig will survive.

The sloth drinks last.

I'm assuming you're talking about land mammals, as if we threw a dolphin and a whale in there, they'd most certainly just turn into food for the tigers.

Are we considering the animals that get stepped on or eaten in the process to be "drinking last?"

mice? rats?, worms:p??

something like that, the biggest coward will drink last

If you put one of every species of mammal you can think of in the cage, automatically, a foodweb will be formed except that there is no plant at the bottom.

Assuming that the pond water last forever, the plant-eaters at the bottom will die first, including giraffes, horses zebras, and even elephants. After which they become food for scavengers and other carnivores. After all plant-eaters had died, the big carnivores will turned on each other and only the strongest will survive, probably a tiger or lion.

Assuming that the tiger survive, he will now be alone with mices, rats and other such scavengers which has all along took advantage of the situation. The tiger now can't hunt because he is injured after that big brawl with the lion. Sooner or later, he will die off and the mices will feed on him.

After that, I suppose the fittest and strongest of the scavengers will survive be it rat or mice. That little guy will be the last to drink.

How about trying to escape?

Man did. He escaped while others fought to their death. He was smart enough to know that fighting leads to nothing.

Chimpanzee. Has greater agility and speed than man, so stands a better chance of reaching the cage walls. Once there, has greater climbing ability, and is more suited to survival 'off the ground'. Could scavange the dead animals as omnivorous. Man would be cut down on his attempt to reach the cage perimeter.
