Ok, the title doesn’t make much sense if you don’t own a pet koala (and I’m ready to bet my dinner you don’t, as it’s illegal). Unless you are a landowner in Australia and have koalas roaming (or rather sleeping 18-22 hours a day) around your properties. The funny looking creatures who are not actually bears (I know! It was a shock to me too!) have their characteristic aroma of cough drops – that’s because their diet comprises of eucalyptus leaves only.
