So since relocating one thing we left behind was a DrinkWell Fountain for Angie the cat. And with three cats in the house water tends to run out before we realize it.
Now the way my friends living room is setup there is a sectioned sofa with an ottoman or hassock or whatever in leather. Well someone had a big cup of ice water on there and it was close to the sofa enough that Angie the cat just walked on and was lapping the water out of his cup.
She was shooed off and the water replaced. But I guess as a cat it was ok when she was thirsty to drink her humans water. Cats are like that. What she does mostly at her age is sleep though.
