You've probably seen news reports about the couple who fed their cat a vegetarian diet. Although I believe in individual rights, this couple
took things too for Cats are natural carnivores, which means they only
eat meat. By changing this necessary part of the cat's diet, the couple
caused serious health problems for the animal. Yes, it's true that meat
based commercial cat food can be expensive, but responsible pet
owners must consider the costs before adopting a cat. Personal
preferences about food should stay personal and not be inflicted on
animals
