However jee asked pourquoies cats keep jumping on tap ... Well I found! The water warms quickly. I think the heat engine and suddenly the plastic also. I tried putting ice cubes (4 main and 2 ds ds tray tank), they all melted in less than a minute.
But my cats appreciate qd same lot. I'm just ds the obligation to change all the water every day to add unz where much of very cold water.
