Why is it ok to be concerned about an overweight pet, but rude to be concerned about a fat's weight? No seriously, other than the idiots who think that their chubby pet is cute, I've only ever seen people reacting to their overweight pet's weight with absolute seriousness and putting the poor thing on a diet. Whereas if you try to be concerned about any other family member's weight, it's rude or it's uncalled for. What bullshit! I mean, if I had to guess, it's because it's easier to control how much your cat eats than it is to control how much a fat eats. Plus your cat wouldn't be able to be sensitive about its weight or cry about how difficult it is to not eat a whole pie in one sitting. As an aside, I also will never understand why fats want to stay fat. I've seen drug addicts and alcoholics with more of a motivation to get better than any fat I've ever known. Even the pigs who are supposedly dieting.
