I sure am glad to find this out, I was really worried about how cat’s drink.
4 engineers with not a hell of a lot to do.
Don’t worry, their secret of purring is still safe.
Well, at least you now know how the Stimulus funds were spent.
BTW, I ran my own test without any Stimulus funding.
I keep two water bowls side by side on a tray in the corner of my den/office for my cats (this is their only source of water except for a slowly dripping tap and the toilet bowls). In one, I pour water from the faucet and in the other I pour only filtered water (Brita). I have 5 cats and they drink a lot of water collectively. Both bowls are changed and cleaned daily.
Results: The one with the faucet water never gets used...and the one with filtered water is almost always half-full each morning.
