When an older cat starts dropping weight, it is worrying, and a calorie-dense supplement can help fill the gap while you work out why. We compared high-calorie gels, muscle-support formulas, and nutritional boosters, focusing on calorie density per serving, palatability for finicky seniors, and supporting nutrients like taurine. In our evaluation we relied on manufacturer specifications, published feline nutrition guidance, and aggregated owner feedback. Here is the honest part: unexplained weight loss in a senior cat is often a symptom, not the problem. Kidney disease, hyperthyroidism, dental pain, and diabetes all cause it. We strongly recommend consulting your veterinarian before relying on a supplement, so you are adding calories on top of a diagnosis rather than hiding one that needs treatment.
