The pen-tailed treeshrew (Ptilocercus lowii) is a species of treeshrew in the Ptilocercidae family. It is found in Indonesia, Malaysia, and Thailand.[2] It is the only species in the genus Ptilocercus and the family Ptilocercidae. All other treeshrews are in the family Tupaiidae.[1]

The pen-tailed treeshrew is the only known wild mammal that chronically (i.e., not just occasionally) consumes alcohol.[3] A study of the treeshrew in Malaysia found that it spends several hours consuming the equivalent of 10 to 12 glasses of wine with an alcohol content of up to 3.8% every night drinking naturally fermented nectar of the bertam palm.[3] Despite consuming relatively large amounts of alcohol, the pen-tailed treeshrew does not become intoxicated. Measurements of a biomarker of ethanol breakdown suggest that they may be metabolizing it by a pathway that is not used as heavily by humans[4], a fellow member of the grandorder of mammals Euarchonta.
