The illness is caused by feline viral rhinotracheitis (FVR) or by feline herpesvirus (FHV). A cat cold is especially dangerous for kittens or adult cats with other ailments that weaken the immune system as well as for animals suffering from stress. The cold is typically triggered by stress, malnutrition, other infectious or non-infectious diseases, very young age, injury, or postoperative conditions. How is it treated? Give your cat IMMUNO BOOSTER with L-lysine, an immunostimulant that alleviates clinical symptoms and boosts the animal’s immune system. Add the flavoured tablets to your cat’s bowl with a small amount of food, or feed them by hand. Use them not only in times of illness but also as prevention in stressful situations. Keep in mind that travel and moving to a new home, for example, can be stressful experiences for your cat.
