I have skimmed this and not found anything prohibiting the keeping of cats and ordering their destruction, but maybe I have overlooked something. (Correction is welcome). But the main thing is that before reaching the Catholic countries in Western Europe the Black Death ravaged the Near East and the Balkans, regions where the Pope had no say. It is thus anachronistic to blame the plague on the Pope.

No.
Vox In Rama was aimed at satanism in Mainz. ( https://museumhack.com/black-cats-black-death/ )
the proximate cause of the Black Plague was the medieval economic over extension and collapse. This left a large concentrated low calorie marginal population with poor reserves. This was of course exacerbated by war and misrule attendant upon economic collapse. See the greater plague resistance in areas sparsely settled due to a lack of economic boom in the 1200s: Poland.
the obvious immediate cause of disease couldnβt have been regulated by rat reduction through catting for the predatory relations described in comments. Ratting was best done by experts with small dogs. Given the variety of densities of ratting quality expectable across Europe, and the strong link between plague resistance and low population / economic complexity, ratting doesnβt seem to have had an effect historically.
