Fetch

That Fetch should be drawn to a saucer of milk speaks to his origins as part Fae:

Samhain, the Gaelic festival that later evolved into Halloween, was a particularly important time for the Cat Sìth. It was believed that during Samhain, the veil between the living and the dead was thinnest, allowing the Cat Sìth to cross over and roam the earth. People would leave out saucers of milk to appease the Cat Sìth, hoping to receive its blessing. Those who did not offer milk risked being cursed, having their cows’ milk dry up.
