Debunking the myth of L-lysine benefits for cats

Cats with FIP, those that have been exposed to and have the coronavirus and those who are at risk of developing FIP should never be given Llysine. The reason is clear. Arginine is necessary for a good, healthy immune system. As explained, Llysine prevents arginine from being taken up in the body.”

There are certain buzz words in the feline community, and one of these is L-lysine. On many cat groups, as soon as mention is made that kitty has a compromised immune system, someone will shout out “L-lysine!” And while L-lysine has anecdotally been thought to help with feline herpesvirus, it is in fact to be avoided at all costs for cats especially those with suspected FIP, cats infected with the coronavirus and those who are at risk of developing the FIP.

It is a fact the science will keep changing and unveiling new discoveries, and that is the beauty of science – that it will keep changing for our benefit. And our duty is to keep up with the changes and not remain stuck in the past.

Arginine, a major building block in a cat’s defensive system, is an amino acid that is essential to maintain a cat’s immune system and immune function. Arginine is not only essential for a healthy immune function, but it is also important in the process of urea synthesis. Arginine is also involved in the excretion of ammonia, blood vessel relaxation, and hormone release, making it an important component of your cat’s diet.

For the adult cat, an arginine-deprived diet is life-threatening.

Natural sources of arginine

Luckily Mother Nature does look after her own and arginine can be found in a number of food sources which lend themselves well to cats, who are obligate carnivores. Raw meat is one of these and adding a spoonful of this every couple of days to kitty’s diet – or even as a treat – will keep those arginine levels up and doing their job. Cats are well looked after as meats are abundant in arginine as are organs. Another rich source of arginine is gelatin. Always remember though when feeding organs that some also contain high levels of other nutrients which in high quantities can be toxic – such as liver which is high in Vit A.

It is always best to double check quantities with a veterinary nutritionist.
