Subsequent to manufacturing errors of the 1950s, the public has been warned that without taurine cats will die. However, the meat in these early canned foods was processed at such extreme temperatures that the taurine was so badly destroyed that cats were unable to maintain healthy life functions – heart disease and retinal damage being the most common effects of feline taurine deficiency. Some cat foods contained predominantly plant protein (meat was ear-marked for soldiers) while others did contain meat. Mass-production was synonymous with experimentation of ingredients and sources. The 1950s was when mass-production of pet food, all foods really, began. In fact, the mouse has the highest level of taurine of any meat source tested to date. These prey animals contained (obviously) meat, therefore taurine. Prior to the 1950s, cats ate whatever they caught – rodents, birds, small prey like rabbits and squirrels. Taurine is naturally occurring in meat – in ample concentration for ALL feline life functions. In the 1950s, researchers discovered cats consuming taurine deficient diets would develop heart disease, along with other lesser known effects like infertility and blindness. Amino acids are the smaller parts that make up protein protein digestion releases amino acids to the body for essential functions including building muscle. Taurine is a sulfur containing amino acid that dogs and humans can synthesize from other dietary amino acids-but cats cannot.
It is a well established fact that cats must consume taurine in their diet.
