Taurine in a cat's diet: What is it and why is it essential to feline feed

In response to a recent post titled "Cats eating people food" our friend Kathy commented, adding a very important sideline for pet and cat lovers to be aware of when considering a cat's diet: the presence of taurine in kitty's meals! I used to hear quite frequently that cats benefit more from their own cat food rather than sharing a meal prepared for pet parents but I never really knew why. I do know that recently caring for so many homeless cats who hadn't received  the balanced cat diet contained in most well known brands of feline feed, that many had serious respiratory infections that caused them to wheeze, have problems breathing and the all too common weepy eyes which seriously impacts their vision and eventually their lives! At this point, they really need antibiotics but I tried to minimize early symptoms by crushing up an amino acid called Lysine and mixing into their food.  As Kathy pointed out, amino acids are imperative for cats and as outlined below, it is typically present in most of your cat food brands, so if you do provide people food, be sure to supplement with their cat food as well.
Taurine is an amino acid that is required for many cellular functions. Cats can synthesize (manufacture) taurine in their bodies; however the rate of synthesis is low and taurine supplies are used up quickly. Taurine is produced in the liver and then absorbed into the bloodstream from the small intestines, it is found in highest concentration in the heart, central nervous system (CNS), retina, and skeletal muscle.

Why do cats require taurine?

  • To maintain integrity of photoreceptor cells in the retina of the eye,
  • To support proper development and functioning of neurons in the cental nervous system,
  • To sustain heart function ,
  • To bond bile acids.

Causes of Taurine deficiency in Cats

Feline taurine deficiency is a syndrome most commonly caused by inadequate intake of taurine in the diet. Cats eating an improperly balanced diet or a vegetarian based diet are most susceptible. Other less common causes are loss of taurine via the intestinal tract and insufficient production of taurine (synthesized by the cat). Most commercial cat food diets are nowadays supplemented with taurine to provide a balanced diet.

Taurine deficiency most commonly results in an enlarged, weakened heart. This condition is usually reversible with taurine supplementation. Deficiency can also cause blindness, poor growth and diminished reproductive performance.

Symptoms of taurine deficiency

  • Heart disease - Taurine is necessary for normal function of the heart muscle cells. Taurine deficiency leads to weakening of the heart muscle, which in turn can lead to heart failure. This condition is known as dilated cardiomyopathy and can be fatal.

  • Blindness - If insufficient taurine is present, the retinal cells can’t function properly and this eventually leads to impaired vision and in some cases, blindness.

  • Reduction in growth

  • Reduction In reproductive performance

Prevention - Checking your cat’s diet

If your cat’s diet is primarily made of high quality animal protein it will contain taurine as this is found naturally in animal-based proteins. Taurine is added to manufactured, dry cat foods that are low in animal-based protein. Wet cat foods are supplemented with twice the amount of taurine found in dry food for cats to maintain adequate blood taurine.

Ingredients labels will only list taurine if it has been added during the manufacturing process, therefore, taurine found naturally in animal based proteins will not be listed.

The best way to ensure your cat is receiving a nutritionally balanced diet is to ask your vet to recommend a food suitable for your cat taking into account age, breed, activity level and any illnesses or problems which may be able to be corrected through diet. In most cases, complete and balanced diets are scientifically formulated to provide all the nutrients to meet your cats dietary needs and ensure sufficient levels of taurine.

    Microchipping your pet: Is it the best way to keep track of your wandering loved one?

    Up to 8 million animals end up in shelters every year. Unfortunately only about 20% of dogs and less than 2% of cats are ever reclaimed by their owners. One way to increase the chances of finding your lost pet is by having a microchip implanted.
    • It's quick! Implanting can be  done in seconds. It doesn't have to be done by a veterinarian but it is recommended, since it does matter where you put it and how you inject it.
    • It's almost painless! It hurts about as much as getting blood drawn. It is a large needle so there is a pinch. 
    • It's affordable! If you are going to the vet for just one microchip the procedure will be about $50. Scheduling the procedure with your pet's routine check up or other treatment will probably cost even less because you have already paid for the office visit. Local animal shelters and rescue groups do it for less so it might be worthwhile to check it out.
    Louise Murray, DVM, director of medicine at ASPCA's Bergh Memorial Hospital in New York City explains how micro chipping works:
    What is Micro Chipping:
    A needle is used to place a little chip under the animal's skin, usually between the shoulder blades. The chipm as a unique number on it that can be picked up and read by a scanner.
    Will the Chip help me get my pet back is lost?
    Yes, but only if someone takes them to a shelter or veterinarian's office to be scanned for a chip. Some people think it is like a tracker or GPS device but it only works if scanned.Once they get the chip number and the company that made the chip, the shelter or staff will contact that company to find the owner. Remember to keep your contact information current otherwise they will not be able to locate you.
    Do all scanners used by Shelters pick up all microchips?
    No, there are more universal scanners now but some work better than others. Not all shelters have universal scanners that work well and the personnel using the scanner need to know how and where to scan. Chips can migrate so they need to scan the body thoroughly--easier said than done sometimes.
    Do all Shelters scan for microchips when they find a pet?
    All Shelters should scan a pet and they should do it with a universal scanner but there is no guarantee that all shelters do this.
    If my pet is micro chipped does he need a tag too?
    Yes, A microchip is only part of your pet's identification system. Your pet should also have a collar with tags on it. You can't assume that the person that finds your pet will know anything about microchips but if your phone number is right there everyone knows what to do.
