A Polish scientific institute has categorized home cats as an “invasive alien species.” 

The Polish Academy of Sciences has outlined the home cat (Felis catus) as “alien” because it was domesticated within the Center East and has deemed cats as “invasive” because of the “damaging affect of home cats on native biodiversity,” they defined in a press release. 


The Academy has a protracted checklist of animals they deem an “invasive alien species,” together with Japanese knotweed, raccoons, clearwing moths, and mandarin geese. 

They state that such species pose “an unpredictable threat to native wildlife,” citing a research displaying that cats in Poland kill and eat 48.1 and 583.four million mammals and eight.9 and 135.7 million birds yearly. 

The factors for together with the cat amongst alien invasive species “are 100 % met by the cat,” Wojciech Solarz, a biologist on the state-run Polish Academy of Sciences, informed AP.

Cat house owners and cat-lovers have expressed outrage on the classification, involved it would incite the abuse or mistreatment of home cats. 

Some media reviews that given the misunderstanding that the institute was calling for feral and different cats to be euthanized, AP reported.

Feedback on the Academy’s Fb web page see individuals saying the establishment’s classification is “merely silly and dangerous,” with one saying, ” you suck and are unworthy of your title.”

Chatting with AP, Wojciech Solarz, a biologist on the state-run Polish Academy of Sciences, mentioned he was not anticipating such a response to including the F. Catus to the database, saying that no different entry has triggered such an emotional response. 


Such was the furor that Solarz confronted off with cat champion Dorota Suminska, the creator of a guide titled “The Glad Cat,” on nationwide TV.

Suminska, a vet, mentioned, “Ask if man is on the checklist of non-invasive alien species” when discussing shrinking bio-diversity. and argued that cats had been unfairly assigned an excessive amount of blame.

Solarz steered that the damaging suggestions could also be from a misunderstanding, whereby individuals suppose the Academy is implying that folks hurt their cats.

The Academy solely advisable cat house owners restrict their pets’ time outdoor throughout chook breeding season.

In a Fb publish, earlier this month, addressing the classification and the following criticism, the Academy mentioned they’re “against any animal cruelty.” It defined that defining the home home cat as an invasive alien species doesn’t warrant any abuse in opposition to them, nor does it justify abandoning cats.
