Xanthosomas would not make good koala food, then.

Young, tender leaves of only some sorts of eucalyptus trees, such as Red River Gums, Ironbarks and Bluegums, are required to satisfy the dietary needs of sleepy, asocial koalas.

Zinnias are edible as well, but I don't think koalas eat them.

Any plant other than eucalyptus is not suitable for koalas just as pandas can only eat bamboo shoots.

But, why do you suppose that is?

Causes may range from the green color of the leaves to the texture of the leaves and the wood.

Dry green grass is usually healthy for horses.

Every animal's digestive tract is designed to handle different substances.

Food supply is a major, and overriding concern of all animals, especially when they are not pets or animals in zoos.

Good point, Wagga.

Hunger is probably one of the strongest motivations for almost everything done on this Earth, even the way humans behave.

I'm getting hungry just thinking about it!

Keeping the conversation about food would do that, Mr. gazer.

Just in case you forgot the letter J, jaguars and jackals would not be too averse to dining on humans.

Lunchtime, methinks.
