Physical condition (also hangover) after excessive consumption of alcohol, a intoxication. The meaning is unclear, according to one of the versions it is not derived from the animal, but from a sloppy pronunciation of the word "catarrh", which was once used in common parlance for general discomfort and headaches. An old popular term for a state of intoxication was "drunk as a cat". Since hangovers or cats (animals) are not potential alcoholics, this is actually absurd. Possibly, however, this has a relation to the basement cat. The condition manifests itself through migraines, severe headaches, dizzy spells, trembling, stomach aches, heart rhythm disturbances, nausea, reddening of the skin etc. Recent studies have also proven negative influences on the necessary dream sleep phase (REM sleep = Rapid Eye Movement).
