Most recently, we had two cats that we picked up as kittens. One was dark grey, the other orange/yellow. Being brunette and redhead females, naturally, we named them Deanna and Beverly (that'll make sense if you're a Star Trek geek). For YEARS, I had trouble remembering their names! Had to THINK about it, every time. (oh, this one is orange... that's... uh... Dr Crusher... Beverly) Good thing cats don't care what you call them.
Now, we've lost the Beverly to Feline Leukemia, and just have her sister... and I've all but forgotten her name! She's just "the cat", and she's whiny as hell. She responds more to tone of voice than specific words. Even sounds work just fine for her. If I catch her whining out in the living room while I'm lying in bed, all I have to do is rub my thumb and index finger together and make the very slight sound. She'll hear it and come running, I'll pet her for a while, and she'll chill out.
We mostly call this one "stupid cat", her sister was more the "evil cat". This one is literally stupid. Her sister, if she was hungry (or just bored and felt like eating or scrounging), she'd jump up on the counter, find any cat food, treats, a loaf of bread, bag of chips, slice of cake (she loved late night carbs), and no electrical cord was safe! She loved to chew through phone charging cords. This one, if her food bowl is empty (sometimes even if it's not), she'll just whine. We often feed her a half can of food, and the other half can is on the counter with a piece of plastic wrap over it. She won't apply any thought. She won't explore. She'll just whine! Dumb as a brick. On the plus side, she doesn't chew up cords.
What's the most money you've ever spent on a piece of art? Did you "commission" it, or was it something you found in a store? My crazy wife is currently having a full wall mural (8 x 24') painted in her new "greenhouse" screen room. It's going to take 2-3 weeks to complete, you can imagine what that's going to cost. But, she can afford it, and it makes her happy. Who am I to judge? I buy old sports cars.
