What it is and who makes it
Brit is a Czech brand with a Veterinary Diet range. Gastrointestinal for cats is designed to settle the gut quickly and make up for impaired digestion. Its high energy density delivers the needed calories in a smaller volume, which matters when a cat eats little. It's contraindicated for kittens and pregnant or nursing cats.

How much and how to feed
Consult a vet before starting and before extending the course. Per the instructions, feed it for 1–2 weeks for acute intestinal upset, 3–12 weeks for digestive disorders, and until optimal weight is reached for chronic pancreatic insufficiency. Feed dry or softened with warm water. Split the daily amount into small portions through the day, which is easier on the stomach. Fresh water always. More on routines in how many times a day to feed a cat.
When vomiting and diarrhoea are dangerous
A single hairball vomit is usually nothing to panic about. But if vomiting repeats, the cat hasn't eaten for over a day, is lethargic, has blood in stool or vomit, a painful belly, or diarrhoea lasting more than 1–2 days, see a vet. Prolonged fasting is dangerous for a cat's liver. A therapeutic diet aids recovery but goes together with diagnosis and treatment. Also check the cat hasn't eaten something forbidden; see what not to feed a cat.
Switching to the diet and back
After an acute episode, switch to the diet straight away, then return to regular food gradually over 5–7 days by mixing. Give no treats or table food during the course, as they undo the diet's effect. If the cat refuses dry food, try softening it with warm water. More in how to switch your pet to a new food.
Who it suits
Adult cats with acute and chronic digestive disorders, pancreatitis, IBD and malabsorption, as prescribed by a vet. Dogs have their own version, Brit VD Gastrointestinal Dog. Other therapeutic foods are in veterinary diets for cats.
Verdict
