There is nothing in eucalyptus leaves that makes koalas sleepy. Eucalyptus leaves are low in proteins and almost indigestible. Koalas have a very low metabolic rate, which is needed to help them digest the leaves and ensure they get as much nutrition as they can from a diet on which other mammals cannot survive.

Can koalas eat eucalyptus?
Yes. Koalas live in eucalyptus trees and eat only a few types of gum leaves from which they get all nutrients and water requirements. They also occasionally eat the gum tree blossoms. Eucalyptus leaves are tough, toxic and low in nutrition, but the koala's digestive system is able to remove the toxins, filtering them out by the liver. The caecum, which is similar to the human appendix, changes the eucalyptus leaves into digestible nutrients. While there are hundreds of different eucalyptus species in Australia, koalas eat from only about 60 of the species, consuming about half a kilogram of eucalyptus leaves every day.
What special features makes koalas able to eat its kind of food which is eucalyptus?
Koalas are specialist feeders, eating only a few types of gum leaves and blossoms from which they get all nutrients and water requirements. Eucalyptus leaves are tough, toxic and low in nutrition, but the koala's digestive system is capable of removing the toxins, filtering them out by the liver. The caecum completes the process by changing the eucalyptus leaves into digestible nutrients. The process takes time, and the koala has a slow metabolism to enable it to process the leaves, gaining as much nutrition and water from the leaves as it can.
What makes a koala so poisonous?
Koalas are not poisonous to either their predators or to man. The Aborigines used to feast on koalas, as they were easy game. There is a mistaken belief that, because koalas feed on eucalyptus leaves, which are toxic, that this makes the koala poisonous if ingested. This is not correct. Some confusion may also derive from people mixing them up with the platypus, which has venomous spurs on its hind legs.
How do koalas build shelter?
Koalas only shelter in eucalyptus trees. They may be seen in other species, but their homes are always in eucalyptus trees. They do not use tree hollows, nor do they make nests. Koalas nestle in the forks between trunk and branches, and shelter within the branches and leaves. This gives them adequate protection from all kinds of weather.

How does a koala adapt to the Australian desert?
Koalas did not need to adapt to Australia. It is the only place they have ever existed. They live in eucalyptus trees and eat only a few types of gum leaves from which they get all nutrients and water requirements. Eucalyptus leaves are tough, toxic and low in nutrition, but the koala has developed a stomach which is capable of removing the toxins from where they are filtered out by the liver. The caecum completes the process by changing the eucalyptus leaves into digestible nutrients. The caecum is similar to the human appendix. The koala must eat over a kilogram of leaves per day to meet its energy requirements. Eucalyptus leaves contain approximately 50% water, 18% fibre, 13% tannins, 8% fat, 5% carbohydrates, 4% protein and 2% minerals. Koalas have been seen feeding in 120 kinds of eucalypt tree including Manna Gum, Swamp Gum, Blue Gum, Forest Red Gum and Grey Gum.

What animals can eat poisonous animals?
It is not a good idea for any animal to eat poisonous plants. Some can tolerate some types and other types will kill them. It's best not to take that chance. Because what one animal can eat quite comfortably could kill an animal of a similar species. On the other hand what is poisonous very much depends on the species involved. Raisins, and to a lesser extent even grapes are deadly poisons to dogs; they aren't considered poisonous to people. At all costs, prevent your dog from eating even one raisin. Koalas live on a diet almost exclusively consisting of Eucalyptus leaves. They contain high levels of the noxious/toxic Eucalyptus oil that makes the plant inedible for just about any other creature, and they contain very little nutritive value. But Koalas thrive on them and can't live without an abundant supply. Possums also eat Eucalyptus leaves but to a lesser extent and it doesn't have any affect on them either. Koalas also only like some types of Eucalyptus tree and won't touch other types.

Why is camouflage important to koalas?
Koalas are essentially defenceless animals which have little other protection apart from their ability to camouflage in trees. Koalas have few natural predators that will climb trees, hut these animals were completely defenceless against the indigenous people of Australia, who were edctive hunters.When koalas nestle high in gum trees, the light filtering past the gum leaves has a dappled look on both the koalas and the gum branches which are similarly dappled. This makes it much more difficult to detect koalas in trees. Their grey fur blends well with the grey-green of the Eucalyptus foliage which they feed on and sleep amongst. The camouflage certainly prevented the early white settlers from even knowing of their existence for the first 11 years of European settlement.
