Cats Need Wet Food!
Cats need to get water from their food
Cats are descended from feline desert dwellers. They couldn't stroll over to the watering hole for a drink, and cat tongues are not very well designed for drinking water.
Cats are adapted to obtain most of their water from their prey, which contains more than 75 percent water. Cats who eat dry food consume only half the water they need, compared to those that eat wet food, and live in a state of chronic dehydration."
Interesting - had heard the opposite actually. This article makes sense though, so maybe my big boy (Turbo) will have to be weaned off the ol' dry stuff (although he likes anything that looks like food, human or cat).
