Specific FID & FIW Digestive Support has been specially formulated to contain highly digestible ingredients which provide an optimum diet for cats suffering with such gastrointestinal problems as vomiting, acute and chronic diarrhoea and flatulence. It contains a select amount of vitamins and minerals which compensate for increased loss of electrolytes due to vomiting or diarrhoea. It is a complete balanced diet which is suitable for both adult cats and kittens.


  • High digestibility - Highly digestible ingredients compensate for decreased intestinal enzymatic activity and ensure an optimal uptake of nutrients. This makes the diet optimal for patients with gastrointestinal conditions such as acute and chronic diarrhoea, vomiting and/or flatulence
  • Vitamin & mineral support - The high content of minerals and fat soluble vitamins compensates for compromised absorption in the patient’s gastrointestinal system. The increased level of electrolytes compensates for increased losses during diarrhoea and vomiting
  • Immune support - Contains β-1,3/1,6-glucans from yeast, which can bind to receptors of white blood cells, thereby alerting the immune system and supporting the immune response. The diet contains mannan-oligo-saccharides (MOS). MOS can bind pathogenic bacteria, thereby preventing them from binding to the intestinal wall, and also supports the local intestinal immunity
  • Intestinal support - Psyllium husk is a gel-forming soluble fibre, which is known for its beneficial effect on the regulation of the gastrointestinal tract activity and protection of the intestinal mucosa
  • Odour Control - Yucca extract reduces the production of malodorous gasses and the smell of faeces

My cat was first given this by our vet after a dental procedure and he loves it. I was really surprised as he is normally so picky.
