We have a tap filter and our cats would rather thirst than drink the filtered
water. They would wait until we took a bath and then drink from the tub. We now
have their bowls in the tub and they drink from that. One of the cats will only
drink from the running tub faucet so we make sure to turn it on whenever we see
him in there. So maybe there is something about filtered water that is
We use one of the little water cooler pet watering bowls. I works great. You could fill it in the bathtub and forget it for a while.
