Inflammatory Bowel Disease (IBD) can affect your cat’s digestion, appetite, and quality of life. It can also be challenging to diagnose. Today, our Simi Valley vets explain more about IBD in cats, including symptoms, causes, and treatments.
IBD in Cats
When your cat’s gastrointestinal (GI) tract becomes chronically irritated and inflamed, inflammatory bowel disease (also called IBD) may develop. IBD in cats does not have a single cause but may occur when inflammatory cells attack the walls of your cat's GI tract.
The GI tract's walls thicken, impairing your cat's ability to digest and absorb food. According to current evidence, IBD in cats can be caused by a complex, abnormal interaction between the immune system, bacterial populations in the intestines, diet, and a variety of environmental factors.
It may take a while to diagnose and properly treat your feline friend's IBD but through dietary changes, medication, and other treatments, your cat can enjoy a great quality of life long-term.
Risk Factors for IBD in Cats
Genetic abnormalities in a cat's immune system, like in humans and dogs, may play a role in the development of feline IBD. Although IBD can affect cats of any age, it is most common in middle-aged and older cats.
Several factors typically contribute to IBD developing in cats. Your kitty's risk factors may include:
- Genetic factors
- Hypersensitivity to bacteria
- Food allergies (such as food additives, proteins in meat, preservatives, artificial coloring, gluten, and/or dairy proteins)
What are the symptoms of IBD in cats?
Inflammatory Bowel Disease is a tricky health issue to diagnose in cats since the most common symptoms can mimic those of intestinal lymphoma, (a type of cancer seen in cats) and other conditions of the GI tract.
You may notice several symptoms in your cat, which can vary in both severity and frequency depending on which parts of the GI tract are affected.
If your cat's colon is inflamed, expect diarrhea with or without blood in the stool, whereas if the problem is in the stomach or higher areas of the small intestine, chronic vomiting may be the most noticeable symptom.
Symptoms of inflammatory bowel disease in cats can include:
- Unexplained weight loss
- Chronic or intermittent vomiting
- Diarrhea
- Bright red blood in stool
- Lack of energy
- Gas (flatulence)
- Gurgling sounds from abdomen
- Abdominal pain
- Coat in poor condition
- Lack of appetite
Diagnosing IBD in Cats
Our Simi Valley vets have several diagnostic tests and methods that can be used when diagnosing IBD in your kitty. Your veterinarian will start by taking a detailed medical history of your cat and asking questions about the frequency and duration of your cat's IBD symptoms.
After a complete physical examination, if IBD is suspected routine laboratory tests may be completed to help diagnose the cause of your cat's symptoms. Your kitty's tests may include:
- Urinalysis
- Complete blood count
- Fecal Exam
- Biochemistry profile
- X-rays
That said, these tests cannot definitively diagnose IBD, however, they are useful in ruling out other diseases (including elevated thyroid, liver disease, and kidney disease), whose symptoms can mimic IBD.
Even if your cat has IBD, these routine laboratory tests may come back normal. Some IBD cats may have an abnormally high number of white blood cells, as well as anemia and abnormal levels of liver enzymes and protein. More tests may be needed to determine how well your cat's small intestine is working.
Abdominal Ultrasound
An abdominal ultrasound may be recommended by your veterinarian to help rule out other diseases that blood tests do not reveal. Ultrasound imaging can also help veterinarians examine the stomach and determine the thickness of the intestinal wall.
Stomach Biopsy
The only way to definitively diagnose your cat's IBD and determine the extent of the disease is to take a biopsy. Stomach and intestine biopsies can be performed with surgery or endoscopy.
Following a definitive diagnosis of IBD, your vet will create a customized treatment plan to help reduce your kitty's symptoms and manage the condition long-term.
Treatment for IBD in Cats
If your cat has not recently been treated for intestinal parasites, your vet may recommend this along with changes in diet and the introduction of medications.
No single treatment is best for treating this IBD in cats, which means that you may need to try several different combinations of medication and diet to find the best therapy for your cat.
Diet
If your cat has an issue with dietary allergens, a hypoallergenic diet may help to resolve your cat's IBD symptoms. Protein or carbohydrate sources the cat has never eaten before (novel protein diets), including venison, rabbit, or duck-based diets may be recommended.
If a novel protein diet does not alleviate your cat's IBD symptoms, a low-fat, easily digestible, a high-fiber diet may be recommended next. Be patient when making dietary changes; it can take several weeks or longer for symptoms to subside. To ensure the diet's success, all other food sources, such as treats, flavored medications, and table scraps, should be avoided.
Medications
Along with dietary changes, medications may be required to help calm symptoms, Metronidazole has antibiotic, anti-inflammatory, and antiprotozoal properties which may help.
Corticosteroids, potent anti-inflammatory and immune-suppressing agents, may be recommended if diet changes or metronidazole prove ineffective for your kitty.
While corticosteroids are usually well tolerated, they must be closely monitored because immune suppression and diabetes are potential side effects. More potent immunosuppressive drugs, such as chlorambucil or azathioprine, can suppress the production of red and white blood cells (and occasionally platelets) within the bone marrow.
Other Therapies for IBD in Cats
Prebiotics (substances that promote certain bacterial populations) and probiotics (bacterial strains to promote GI health) may help balance your cat's GI bacteria and reduce your cat's symptoms of IBD.
Soluble fibers such as psyllium may also be added to your cat's diet for some natural treatments of inflammatory bowel disease in cats if inflammatory colitis is an issue. If your cat is deficient in folate or vitamin B12, your vet may recommend supplementation.
Can IBD in cats be cured?
There is no cure for IBD in cats but, with the right treatment, symptoms can often be managed to help keep your cat comfortable and healthy.
Even with proper treatment, your cat's IBD symptoms may come and go and vary in severity. Strict adherence to dietary restrictions and medications will be required to manage your cat's symptoms. You and your veterinarian will keep a close eye on your cat for the rest of its life.
When relapses occur your cat should be assessed by your vet as soon as possible so that medications and other treatments can be adjusted as required.
