The Benefits of a Taurine Supplement For Cats

As we have seen, taurine is essential for cats, just as vitamins are for us. We cannot produce ourselves, and so we must integrate them with the diet.

The cat must take taurine because it becomes part of a series of bodily development processes in the cat. It includes the synthesis of bile acids, the development of myocardial tissue, and the development of nerve tissue, including the retina.

Important Features to consider

There are many types of taurine supplements for cats. There is taurine in powder form. There are taurine tablets, the paste containing taurine, even drops that contain it.

It is important when talking about food supplements for cats to pay attention to the amount of taurine in the preparation. It is usually not only taurine but also some excipient, put together to hold taurine together.

For this reason, we must take care that the dose in milligrams corresponds to what they need. For example, if a supplement comprises 10% taurine, it means that each gram of the supplement carries 100 mg of taurine. When a veterinarian plans the diet for the cat, just ask him how much taurine to supplement by simply showing the package you have.

Best Taurine Supplement For Cats FAQs

Is too much taurine bad?

From what we have read, as a non-human doctor but only a humble veterinarian, excess taurine causes side effects in humans, probably because of the route of intake which may not be oral. As in the cat to date, we have reported no side effects due to excess taurine.

Is taurine present in cat foods?

Yes, cat foods you buy in supermarkets or pet stores contain high doses of taurine. But these foods must be quality and as natural as possible. There are some made with dehydrated quality meats.

Poor quality foods are an unacceptable option for your four-legged friend for taurine. They contain many seeds and little natural taurine. And the one they contain to compensate for the deficiency comes from artificial sources.

Where is taurine found?

The best option to give cat taurine is naturally. It is by obtaining the amino acid from animal protein sources. Try to choose organic, quality proteins that come from sources that respect the animal world. In each meal, the cat should take between 200 and 300 mg of taurine.
