The majority of medieval British people lived in hovels with thatched roofs with no wood underneath. It was the only place for animals to get warm, so all the cats and other small animals (mice, bugs) lived in the roof. When it rained it became slippery and sometimes the animals would slip off the roof, hence the saying 'it's raining cats and dogs' we use that a lot over here :)
New species of leopard with largest fangs in cat world discovered
