Vegetarians have known for decades that meat is expensive financially and environmentally. That’s because raising animals for food takes water and space, and the animals create manure and methane.

Gregory Okin, a UCLA geography professor and study author, estimates that meat for dog and cat food is responsible for greenhouse emissions equivalent to those of 13.6 million cars. So if you want to save the environment, you can stop eating meat but your cat will keep eating meat anyway.

So how do you keep your cat happy while still protecting the environment? You could start by feeding your cat only the finest caviar and lobster while you survive off beans and rice for the rest of your life. This will cut your environment carbon footprint so your cat can enjoy life at your expense, which is what cats know how to do anyway.
