I know the Norfolk water, S. Limescale builds up quickly… I much preferred the sweet Welsh water that came from the N Wales lakes to taste but I think both areas use a lot of chlorine these days and hard water is supposed to be better for you… Pip won’t drink the straight tap water here and hates it even in a cup of tea. One of those under the sink filters and a little tap at the kitchen sink has been the best answer we’ve had for that It’s slow to fill a jug or kettle from but it removes whatever she finds offensive to the taste.

No accounting for cats' taste though...
