Cat Cardiac Cachexia: Nutritional Support

Cardiac cachexia causes muscle loss in cats with heart disease. Targeted nutritional support can maintain lean body mass and quality of life significantly.

Key Facts

Cardiac cachexia occurs in advanced heart disease due to metabolic and inflammatory changes
Weight and muscle loss occur despite adequate caloric intake in cachectic animals
Taurine deficiency contributes to dilated cardiomyopathy in some cats
High-protein diets are preferred over sodium restriction for maintaining muscle mass
Omega-3 fatty acid supplementation reduces cardiac inflammation and slows cachexia

Welfare Considerations

Cats with cardiac cachexia experience progressive muscle wasting that reduces mobility, thermoregulation and immune function. The weakness from muscle loss compounds the exercise intolerance from cardiac impairment. Nutritional interventions including high-quality protein, omega-3 fatty acids and ensuring adequate caloric intake help slow but not reverse cachexia. Appetite stimulants such as mirtazapine help maintain voluntary food intake during periods of inappetence. Feeding small frequent meals of highly palatable food maximises intake in cats with reduced appetite.

What You Can Do

Feed a high-quality, high-protein diet rather than severely sodium-restricted food
Supplement with omega-3 fatty acids at appropriate cardiac doses as directed by your vet
Use mirtazapine or capromorelin appetite stimulants during inappetence periods
Weigh your cat weekly and report significant weight loss to your vet promptly
Offer small, frequent, warmed meals to maximise voluntary food intake
