You will fall in love with the fountain and forget all about that nasty tap water. Never know what is coming out of them.
My hoomans just installed a rain soft water system. And the fountains they got for us also have 3 way filters.
Us kits, especially older ones like us, need to take care of our kidneys.
So Zap the Tap C.C.
I think you're right!
The Hoomans only put nice clean spring water in my fountain, not tap water, so that's a good start.
And yes, good urinary health is extremely important for cats, particularly as we get older!
