  • Gastroprotectors. H-2 blockers of histamine receptors or proton pump inhibitors. To reduce the secretion of gastric juice;

What to feed a cat with gastritis?

The most important – easily digestible ingredients, fractional feeding, warm food, wet rations. Fractional feeding is recommended, every 2-4 hours.

If the pet is accustomed to industrial diets, then you need to transfer it to special feeds with protein hydrolyzate. Protein in such diets is digested much easier and, accordingly, does not linger in the stomach and intestines, and also does not provoke the processes of food decay.

How to feed a cat with gastritis, if he is used to eating home-cooked diets? It is important to give preference to proteins with a high content of arginine, glutamine, glycine and lysine (seafood, eggs, cottage cheese). If a food intolerance is suspected, an elimination diet may be recommended, meaning that only one protein source will be left. Regarding carbohydrates, you need to limit the intake of non-fermentable fiber, the carbohydrates themselves should also be easily digestible (corn, rice, wheat, barley). Fats in the diet should be limited as much as possible. And the daily need for fats is replenished by saturated fats (fish oil, sunflower oil, avocado).

In order not to have to treat gastritis in a cat, it is important to know how to prevent it:

  1. Proper feeding schedule. Do not give your pet something from your table. The number of feedings should be individually selected. Food should not be too hot or too cold, and of course it should be fresh;

  2. Prevention of poisoning. It is necessary to hide all household chemicals, cosmetics, all kinds of perfume additives, oils, medicines, etc. from the pet. The pet, of course, will not lick the floor after you have washed it with bleach, but it will pass through it and then will definitely lick its paws , so rinse off such substances from the floor after cleaning. Indoor plants must also be removed in places inaccessible to the pet;

  3. Remove all small items. Cats often swallow packages, threads, ropes, etc. in the game;

  4. Do not self-medicate. There are a number of drugs intended for humans, but contraindicated in cats. And those drugs that are shown to cats can be prescribed in a different dosage than to humans;

  5. Prevention of infections and invasions. Regular vaccination. Timely treatment for parasites. Thermal processing of products of animal origin. Restriction of access to the street;

  6. Timely visit to the veterinarian. If there is the slightest suspicion of deviations in the well-being of the pet, you need to contact a specialist in order to start treatment on time.
