Allergies in animals as in humans, recently occur more frequently and is more common phenomenon. However, what is important, as in humans, it also occurs in adulthood. It also happens that the cat has not been allergic to a nutrient, and now it is. It's a very unpleasant phenomenon and very unpleasant disease that not only affects the pet, but with him it usually its owner.
It is important to distinguish food allergy from an indigestion of food or food ingredients. A cat that suffers from indigestion after consuming a component, which it can not absorb, immediately has digestive problems. Has diarrhea, vomits, it can be seen it suffers from digestive problems. Withdrawal from deleterious component causes the cat immediately recovers and returns to its original form. It is practically a healthy cat.
Symptoms of an allergies are slightly different. Cat, after eating an allergen, begins very intensively to scratch, swells, a rash appears. These are typical allergy symptoms that do not disappear immediately after stopping harmful product. The withdrawal is the first step, but to have the symptoms disappeared cat has yet to be treated. Typically, it is enough to give it a calcium, but not always the calcium itself will be enough. So in short looks difference between indigestion of certain products and an allergy to them.
Another problem in case of allergies is that it can occur at any time of life. It can occur at youthful age of the cat and in adult. Even the allergic cat for many years may not be allergic to an allergen, until one day, suddenly, it starts to cause an allergic reaction. It is also important to know that cats can suffer not only from food allergies, but also can be allergic to pollen and dust mites.
How, then to feed an allergic cat? First of all, wisely, in a very carefully planned and controlled way. Cat may be allergic to an insignificant part of their diet, then this component can be simply set aside and we may provide supplementary micronutrient replacing it. However, it may also be allergic to some essential element and then alternatives must be much more carefully selected and matched.
The problem arises, however, when you do not know to what the cat is allergic and you try to feed him so as to put him in the least threat. There are of course many foods specifically designed for cats with allergies. They are full of all kinds of cereals, which rarely cause allergy, are rather less common allergens, are deprived of the most common allergens. There is food without grains at all. The meat in such foods is also non-allergenic. This can be horse meat or duck, because these are very delicate meat and do not cause allergies. Diet with no allergens should be used systematically and persistently. You have to be very strict and consistent, because even one derogate from the diet causes a total loss of what was possible to achieve through diet, and the cat again begin to suffer from causing an allergic reaction again.
Therefore you can see how important is the care with feeding your allergic cat. If you want him to be healthy then you need to be very very vigilant and careful.
