Lysine and taurine are both important factors for feline health. Differentiating between the two can be difficult, as both are amino acids and building blocks for protein. In addition, both are vital for a cat's overall health. However, they are different and play different roles within the body. Thomas Labs® can help you discover the differences between lysine and taurine for cats!

What Is Lysine?

Before we can discuss the benefits of Lysine for cats, it's important to understand Lysine. Lysine is an essential amino acid that serves as a building block for protein, which is essential for many bodily functions like building and repairing cells, producing antibodies, and providing energy.

What Are the Benefits of Lysine for Cats?

There are a wide variety of benefits that Lysine can provide to cats. It helps cats produce antibodies and enzymes that support the immune system. Additionally, it is helpful for calcium absorption, supporting strong bones, and promoting healthy skin. Because a cat's body doesn't make Lysine on its own, cats need to receive outside sources of it, such as through food and supplements.

Veterinarians often suggest giving Lysine to cats to help with various ailments, including viral infections and feline herpes virus (FHV). Studies have shown giving oral Lysine to cats infected with FHV-1 is associated with a significant reduction in the severity of clinical signs and basal viral shedding.

Veterinarians may also use Lysine to help with upper respiratory infections and conjunctivitis if it is associated with the herpes virus.

What Is Felo Lysine?

Felo Lysine from Thomas Pet is a supplement that promotes the production of antibodies and enzymes to support the immune system in cats and kittens. With continued supplementation, Felo Lysine can promote healthy eye function and respiratory function.

What Is Taurine?

Similar to Lysine, Taurine is an amino acid that can have many benefits for cats. It is important for heart health and normal heart muscle function, digestion, and vision. Plus, it helps maintain a healthy immune system and is crucial for a healthy pregnancy in cats.

Cats must receive taurine from their diet because unlike humans, their bodies don't produce it internally. They can receive taurine through animal protein like fresh, unprocessed meat.

However, many cats don't hunt on a regular basis, so they could benefit from a taurine supplement.

What Are the Benefits of Taurine for Cats?

Taurine plays an important role in a cat's body. It is vital for the proper functioning of the body and is required for the healthy functioning of the eyes, heart, immune system, and gastrointestinal tract. It is also beneficial for a cat's teeth and hair.

When cats don't receive enough taurine, they may start to show symptoms of taurine deficiency, which can lead to life-threatening issues in cats. Symptoms of taurine deficiency in cats include vision problems, heart failure, digestive issues, and even death. It can also lead to weakening of heart muscle cells, causing a condition called dilated cardiomyopathy.

Choosing a high-quality cat food and making sure that taurine is listed as an ingredient in your cat’s food can help ensure your cat is receiving taurine.

What Is Felo Taurine?

Felo Taurine from Thomas Pet is a water-soluble taurine supplement for cats. This easy-to-digest supplement helps support digestion, cardiovascular health, eye function, and normal vision, as well as maintain a healthy immune system.

Although different, both lysine and taurine play vital roles in feline health. Ensuring your cat is receiving enough of these essential amino acids is important for their overall health!
