Search the Internet and you can find stories of cats weighing as much as 47 pounds. If your cat weighs too much, you need to put it on a weight loss program that involves diet and exercise, which are two parts of any weight loss program that even humans tend to avoid if possible.
For a cat in Dallas named Skinny, his weight ballooned up to 42 pounds before a bet put him on a rigid diet and exercise program. Besides reducing his calorie intake, Skinny now spends 15 minutes a day on a treadmill. If you think your cat eats too much, you can put him or her on a weight loss program like Skinny. Then again, you might as well just wait for your cat to rip open your throat if you fail to do its bidding, so the choice is up to you.
