Freedom hit on some good points. AND, most vets know doggie-doo doo about pet food.

Every am, I give all ten of my cats a smidge of wet food. A tuna sized can gets divided. And, I don't believe for a moment that gets enough water into them. But, for one of the cats, the one that does have signs of kidney failure, his is made into a soup. He drinks it. I also have a water fountain AND I leave my tub dripping. :-0 Yup. I know they drink from it as I see them in there all the time, there are wet heads all the time, and paw prints on the floor.

Cats don't prefer their food bowls next to their water bowls. I also have water out for them that isn't next to the food.

Let us know what you hear back from the tech!
