Speaking of witchcraft in the British Isles, cats in Ireland would eventually be associated with it but that’s a later development perhaps owning to both English colonisation starting with the Anglo-Normans and repeat famines. The earliest case was that of Alice Kyteler which also mentioned a black dog.
Again, here’s a close association between black dogs and witchcraft but surprisingly in medieval Ireland it wasn’t that frequent. One could make an analogy with DR Congo. There were some folkloric association of cats (and dogs) with something bad before but it wouldn’t get widespread especially in Kinshasa until DRC’s economy worsened for several decades.
Ireland has been through many famines, the earliest in 1310! It’d worsen when Gaelic culture and politics were marginalised. For another matter, a decade long war in Rwanda soured them on dogs. That’s how the Irish felt about cats in the last three centuries or so until recently.
It seems as late as 1725, especially in Dublin (when outside of Northern Ireland, a Scottish plantation) cats would be linked to such practises that it’d become widespread in the 19th century ironically around the time when Continental Europe’s lessening that superstition.
Again, blame bad socioeconomic conditions not unlike that of DRC.
