That you-tube video makes me laugh. My old girl siamese cat will be 19 years old in a couple of weeks. She is going deaf. Arthritis in hind legs. She can't walk on the tile because it looks like she's on ice - with legs going out from under her. She's happy, purrs, loves attention, patient. But in the AM she yeows. If I don't feed her by 7:30, she won't let me sleep. It's LOUD. We wondered if it's because she can't hear herself. So at least I know that Bun isn't the only ole' kitty that is vocal.
