Understanding Irritable Bowel Syndrome and IBD in Cats
Chronic digestive symptoms in cats, particularly vomiting, diarrhoea, and weight loss, are often eventually attributed to inflammatory bowel disease (IBD). It's one of the most common diagnoses in middle-aged and senior cats with persistent gut issues, and it's also one of the most misunderstood.
What Is IBD in Cats?
Feline IBD is not a single disease but a group of chronic inflammatory conditions in which immune cells infiltrate the walls of the gastrointestinal tract. Depending on the type and location of immune cell infiltration, different clinical patterns emerge. The most common forms are lymphoplasmacytic enteritis (the most frequent type), eosinophilic gastroenteritis, and neutrophilic inflammatory disease.
The diagnosis is confirmed by intestinal biopsy, typically obtained via endoscopy or exploratory surgery. Blood tests, ultrasound, and clinical presentation are all supportive but not definitive.
IBD vs Irritable Stomach in Cats
Cats with an irritable or sensitive stomach produce recurring digestive symptoms, often without the degree of immune cell infiltration or structural gut wall changes that characterise true IBD. The distinction matters because treatment approaches differ and the prognosis is different.
A cat with a sensitive stomach and underlying gut microbiome disruption may respond well to dietary management and probiotic supplementation. A cat with confirmed IBD typically requires immunosuppressive medication (most commonly prednisolone) alongside dietary management, and probiotic supplementation as an adjunct to reduce inflammation and support gut lining integrity.
The Gut Microbiome and Feline IBD
Research consistently finds altered gut microbiome composition in cats with IBD compared to healthy cats. Specifically, reduced populations of beneficial bacteria including Faecalibacterium and increased populations of potentially pathogenic bacteria. Whether this dysbiosis is a cause or a consequence of IBD is still debated, but the bidirectional relationship is clear: a disrupted microbiome feeds gut inflammation, and gut inflammation disrupts the microbiome further.
Probiotic supplementation in cats with IBD is supported by growing evidence as a complementary approach to reducing gut inflammation, restoring microbial diversity, and improving short-chain fatty acid production that supports the gut lining.
Managing Chronic Digestive Issues in Cats
Veterinary diagnosis. Persistent vomiting, diarrhoea, or weight loss in a cat should always be investigated. IBD requires biopsy for definitive diagnosis and appropriate treatment.
Diet management. Novel protein or hydrolysed protein diets reduce antigenic stimulation of the gut immune system. Highly digestible, low-residue diets reduce the burden on an inflamed gut.
Medication. Immunosuppressive medication, typically prednisolone, is the cornerstone of IBD management in cats. Vitamin B12 (cobalamin) supplementation is often needed as IBD impairs B12 absorption.
Gut microbiome support. Daily probiotic and postbiotic supplementation reduces gut inflammation, supports microbial diversity, and helps maintain gut lining integrity alongside primary treatment.
Ipromea for Cats with Chronic Digestive Issues
Tummy Time Liquid Probiotics for Dogs and Cats (500ml)
The liquid format is the most practical way to deliver daily gut microbiome support to a cat with IBD or chronic digestive symptoms, particularly during periods when appetite is reduced. Pour over food once daily. Safe to use alongside prednisolone and other IBD medications. The Zoonatant postbiotic technology provides direct anti-inflammatory support through the gut lining independently of live bacteria activity.

Frequently Asked Questions
Can IBD in cats be cured?
IBD in cats is generally managed rather than cured. Many cats achieve excellent quality of life with appropriate management including diet, medication, and gut health support. Some cats go into prolonged remission. Without management, IBD tends to progress.
Can probiotics help a cat with IBD?
Evidence supports probiotic supplementation as a complementary approach in cats with IBD. It does not replace primary treatment but reduces gut inflammation, restores microbial diversity, and supports gut lining integrity alongside the primary management approach. It is safe to use alongside prednisolone and other IBD medications.
My cat has been diagnosed with IBD. What should I feed them?
Your vet will guide dietary management based on your cat's specific IBD type and response to treatment. Novel protein or hydrolysed protein diets are often recommended. High digestibility, low residue, and consistent feeding of the same food are general principles. Avoid dietary changes without veterinary guidance during active IBD management.
