My Tigger will only drink water from the faucet. It can be from the tub, the bathroom sink or the kitchen sink but other than that she drinks NO water.

I would continue with the watered down food. A sign of dehydration is a loos of skin elasticity. When the skin along the back is picked up into a fold, it should spring back into place. If the cats are dehysrated the skin will stay up in a ridge. They will also be dry in the mouth and the gums will be dry and tacky to the touch.

Hope that info helps.
