On a drinking, but non-alcohol, related note, Domino, who has been refusing to drink water for over a year (we've been having to give him iv fluids every other day) suddenly began drinking water freely. What was the change? We filled his favorite water bowl with tap water. He had been refusing both bottled and filtered water all of this time, preferring to drink out of the toilet (we've kept the lid down for this entire time, as well, and still do).
I may have posted this before, but I had a cat who lived until he was 16 and never, ever drank a drop of water.
He only ate canned food, even though I got him at eight weeks, he never changed his habits. His sister loved dry food and would drink water as needed.
We had a little war where I tried to get him off canned food, but he went five days without anything, while his sister was happily living her life. I finally gave in, he won the battle and he lived the rest of his life on canned food, which has a lot of water, so he was fine not drinking water his entire life.
One of the coolest things he ever did, probably repeating myself here, but he was sitting on a bar stool watching me prepare dinner. A fly had gotten in and was buzzing around driving me crazy. The fly came at my cat at just the right angle and he literally just stuck up his paw like a baseball mitt, caught the fly and ate it. Totally amazing, wish I had caught it on video.
