I have a feeling that is not the reason for the new classification in Poland.
They don't want women to become spinsters with a dozen cats, now that they outlawed abortion.
I don't think they will keep women from staying single by outlawing cats, but I would not be surprised if it was the intention.
Sorry but this is reaching. Scientists having an opinion that cats should be kept indoors is just that.
People don't usually like changing their lifestyle for the planet but they will have to. Pets are really bad for the environment in general
