I was looking through some medieval manuscript marginalia again and noticed that rabbits were also very popular but in those times they didn't seem to see them quite as we do. They must have been much less cuddly then.
And if the snails were often depicted being attacked by or fighting the knights, the rabbits appear to be way more sinister and are usually shown capturing, killing or torturing humans.
And it was not only humans the evil bunnies had beef with, they were not fond of the hounds too it seems.
But there were some nice and cute ones in those times too.
