Did the ancient Celts sacriﬁce cats because they hated them? Not necessarily. Even the cat-loving Egyptians sacriﬁced cats. Why the Celts chose to burn huge numbers of cats is not known. It appears that Celts, like other ancient people, associated cats with fertility, and so a mass sacriﬁce of cats to the gods of fertility had a certain odd logic to it. We still have a lot to learn about the Celts.
