Some cat lovers have reacted emotionally to this month's decision and put the key scientist behind it on the defensive.
Wojciech Solarz, a biologist at the state-run Polish Academy of Sciences, wasn't prepared for the disapproving public response when he entered "Felis catus," the scientific name for the common house cat, into a national database run by the academy's Institute of Nature Conservation.
The database already had 1,786 other species listed with no objections, Solarz told The Associated Press on Tuesday. The uproar over invasive alien species No. 1,787, he said, may have resulted from some media reports that created the false impression his institute was calling for feral and other cats to be euthanized.
Solarz described the growing scientific consensus that domestic cats have a harmful impact on biodiversity given the number of birds and mammals they hunt and kill.
The criteria for including the cat among alien invasive species, "are 100% met by the cat," he said.
