My pet will not drink water from the tap. Absolutely refuses. Will look at the bowl of water and back at me, then back to water, then look at me again as if to try to communicate something. Then, runs outside and goes immediately to a dish of rainwater or stands at the birdbath.
I suspect the tap water has flouride.
I wonder if animals have a keen sense to know something is not right about it?
My pet will not drink distilled water, either.
My pet will only drink spring water from a bottle or rainwater outside.
Does your pet show any aversion to tap water?
