Oh the painkillers...sorry forget! LOL

If the vampire bats can indeed sleep in the sun, and they can hang at center of the roof, vampire bats will survive.

Tiger: This is unfair! Mr Bat can sleep in the sun. I want to fly too.

No offense intended.

throwing some wood on the fire...

* would it matter if the human could use/make something out
of the bones and carcass of the less fortunate? (if the human would even survive long enough to outlive the herd mammals). sleep deprivation would seem to be a factor as well.

* what about mammals that burrow?

* what are an elephant's chances?

* would a tiger/panther/lion fight each other? is so, which is your money on?

* how about a bear vs gorilla?

* what would be the first to die? I'd say the cow.

If the human outlive the herd mammals by luck, it could use the bones to make weapons. Eg. Swords made from elephant's ribs, deer's anthlers. Problem is, there are no stones or any tools to help the weak human remove the ribs. As such, they can only use limb bones which are blunt serving no use at all.

Since it is an unescapable cage, I presume that either the ground is cement or the cage is suspended in air. Makes no difference if the mammal can burrow.

The elephant will survive until it is starved out. Obviously nothing wants to attack it till it is dead.

They would fight each other for food. I put my money on the tiger since it is the strongest physically.

Bear vs gorilla? Gorilla of course. Bears are temperate and polar mammals. I think they would be weaken as a result of heat stroke in a 20c environment. What's more, the gorilla can climb on the cage as well.

The wild cow is actually a force to be reckoned with. I say the kangaroo dies first.

Are sea mammals included in this big brawl? Wow...a blue whale.

Human dies first.
Trust a human to do some dumb ass thing and try to establish authority by trying to stare down a lion.
Either that or he panicks and gets eaten by the nearest animal just to shut him up.
Humans also have no fur, which is a very attractive prospect for carnivores, and cannot fight back (also a very attractive prospect)

Realisticly speaking I would assume that the big animals such as the big cats and the gorilla, bear etc, there would be a big king of the hill match until the king of the hill would actually reamin but by then would be too exhausted and wounded to actually kill and eat another animal and would die of bleeding to death. In which case ALL that wouldbe left would be the vegetarians, which would get eaten slowly but surely by.....
thats right! the BAT
Humani definetely dies first.

I agree...human dies first. No mention was made of the resources available to human. On his own, au natural, if he doesn't starve, or get eaten he will probably die from simple exposure.

I think the one that will survive the longest would be the mouse.

If we are going to be uber strict on mammals only in the cage, then the burrowing mammals will have no insects/worms to find in the soil, so would starve before the 'overlanders'. A human with a femur versus a hungry lion? no contest. Humans hunted in groups to be effective with rudimentary weapons. One guy on his own is doomed.
Any of the big carnivores could win on any given encounter, tiger vs lion is like liddell vs couture, different outcome each time
As for bear versus Gorilla, I am going with Grizzly bear based on number of weapons and size advantage.

I was thinking along this line. The big carnivores would fight...but only after all herbivores had been killed when resources become scarce...ah..then is war. Bears are out, they would be weaken by the heat, gorillas too by starvation. Leaving the big cats, obviously the tiger wins, which by then be so weak that it can't hunt anymore.

Omnivorous primates can just climb and stick to the cage while watching the big brawls. After one fell, they can swiftly climb down, carry some meat and go up to feast. Eventually the tiger dies, the omnivorous primates survive for as long as till they kill each other and starve out. Well, the bat will continue to drink blood and so will be the eventual winner.

What if our representative turn out to be a strong and smart one? First thing he does, he climbed up the cage to wait and scavange. Eventually, he will be one of the surviving and strongest omnivores. The gorilla appears to be the only primate stronger than the human. The human as the last survivor, may look to the bat up there for food. Who knows, human may be the last survivor?

A fully grown baboon and/or chimp would kick a humans a$$ in a life or death fight

Not really, humans are larger than chimps and baboons.

Heh, trust me my friend, the physical attributes of either of these animals is far superior to our own. Size is not a factor in this equation, different species, different rules. Add to the advantage in power the fact that an adult baboon has fangs as long as 4-5 inches and you have a super fast super aggressive Jack the ripper with a bright red a$$. They dont put barriers up in zoos to prtect the animals from the humans
