We don’t recommend transitioning cats with heart disease onto Marro.
WHY?
Cats with heart disease have unique nutritional needs, especially during the early stages of diagnosis and treatment. While our meals are high-quality, nutrient-dense, and made to support healthy cats, some cats with heart diease may find it difficult to adjust to Marro. This is because their body may not be able to cope with nutritional changes as easily as a healthy cat.
For this reason, we recommend speaking to your vet about a diet that supports your cat's individual condition and stage of care.
ALREADY FEEDING MARRO TO A CAT WITH HEART DISEASE?
If your cat has already transitioned to Marro and is doing well, that’s great! This recommendation only applies before starting our meals due to the challenges that can arise during the transition period for cats with heart conditions.
If your cat is already enjoying Marro and thriving, there is no need for concern. We're so glad they’re enjoying the Fresh life!
UNDERSTANDING HEART DISEASE IN CATS
Heart disease in cats typically stems from changes in the heart muscle, a group of conditions known as cardiomyopathies. These affect how efficiently the heart pumps blood, which can lead to fluid build-up in the chest or abdomen and eventually congestive heart failure (CHF).
TYPES OF CARDIOMYOPATHY
Hypertrophic Cardiomyopathy (HCM): The most common form. The heart muscle thickens, reducing space in the chambers and impairing blood flow.
Dilated Cardiomyopathy: The heart walls become thin and weak.
Restrictive Cardiomyopathy: Scar tissue limits the heart’s movement.
RISK FACTORS
While the exact cause is often unknown, several factors are linked to feline heart disease:
Breed: Ragdoll, British Shorthair, Sphynx, Persian, and Maine Coon cats are more prone.
Age: Incidence increases with age.
Weight: Obese cats are at greater risk.
Hyperthyroidism: Excess thyroid hormone can overstimulate the heart.
High blood pressure: Increases cardiac workload.
Taurine deficiency: Especially linked to dilated cardiomyopathy.
SYMPTOMS TO WATCH FOR
Rapid or laboured breathing
Lethargy or hiding
Loss of appetite
Weight loss
Cold paws or extremities
Pale gums
Swollen abdomen
Collapse or weakness
Heart murmurs
Note: Not all heart murmurs indicate heart disease — and not all cats with heart disease will have a murmur.
