Old cat eats a lot but continues getting skinnier

That definitely sounds concerning, and I completely understand why you're worried. When an older cat is eating well but still losing weight, there could be several underlying reasons. Some common causes include hyperthyroidism, diabetes, kidney disease, or gastrointestinal issues.



Hyperthyroidism is especially common in older cats and can lead to increased appetite paired with weight loss. Diabetes might also result in increased hunger while the body struggles to retain nutrients. Kidney disease can alter metabolism and cause weight loss even if food intake seems normal. Gastrointestinal problems might prevent proper absorption of nutrients.



At home, keep a close eye on your cat’s water intake and litter box habits. An increase in thirst or urination, or any changes in bowel movements, are critical details to note. Ensuring your cat is eating a balanced diet and is free of any parasites, like worms, is also important.



Watch for signs such as vomiting, diarrhea, excessive drinking, decreased energy, or changes in behavior. These could indicate more serious issues that need immediate attention.



You’re doing the right thing by looking into this, and I’d recommend scheduling a video consult with one of our vets on Dial A Vet. They can help decode your cat’s symptoms and guide you on the best next steps.
