7 Key Signs Your Senior Cat May Need a New Diet
Your cat may not be chasing flies like they used to—but that doesn’t mean they shouldn’t feel fantastic in their golden years. As they age, our feline friends go through subtle changes that can have a big impact on their health and wellbeing. If you’ve noticed your senior cat seems a little slower, more sensitive, or just not quite their usual self, their diet might be to blame. In this guide, we’ll walk you through the key signs that your senior cat could benefit from a new diet, and how to choose the right one for their age and stage. At Petdirect, we get pet—and we’re here to help you support your cat’s healthiest, happiest life.
1. Weight Gain Or Loss
A sudden change in weight is one of the most common signs your senior cat’s diet may need a rethink. Older cats often burn fewer kilojoules due to lower activity levels, which can lead to weight gain if they’re still eating a high-energy diet. On the other hand, conditions like hyperthyroidism or kidney disease can cause unexpected weight loss. Either way, it’s a sign their current diet might not be meeting their unique nutritional needs. Consider transitioning to a science health nutrition cat food tailored to support senior cats or a weight management formula if needed.
2. Dull Coat Or Skin Issues
If your kitty’s once-glossy coat is looking a little tired or they’re dealing with flaky skin, their food might be lacking essential omega fatty acids. A change in diet can bring back that silky sheen. Look for meals with added skin and coat support like cat skin and coat health supplements or choose premium foods such as Feline Natural or ZIWI, which include natural oils and high-quality proteins.
3. Slower Mobility And Joint Stiffness
Senior cats may start to show signs of wear and tear in their joints—those mad dashes down the hallway turning into gentle strolls. If your cat is hesitating to jump or seems less agile, their diet might not be supporting their joint health. Food enriched with anti-inflammatory nutrients can help. Consider adding a cat joint support supplement or switching to a senior-specific formula fortified with glucosamine and chondroitin, like Hill’s Science Diet or Royal Canin.
4. Changes In Appetite Or Eating Habits
Is your cat showing less interest at dinnertime? Older cats may develop reduced senses of smell or dental issues that make food less appealing. Try switching to softer textures like wet cat food, adding toppers for added aroma, or opting for supplements that support dental or digestive health to ease discomfort at mealtime.
5. Constipation Or Frequent Diarrhoea
Digestive health can become more sensitive with age. If your cat is straining in the litter tray or experiencing loose stools, their food might not be gentle enough on their tummy. Look for diets with added fibre or probiotics, such as those from Pro Plan or vet-developed options like Hill’s Prescription Diet. You can also support sensitive tums with digestive health supplements.
6. Increased Thirst Or Urination
Frequent drinking or urination could signal underlying health issues, including diabetes or kidney problems—conditions more common in older cats. It may also suggest their current diet is too high in sodium or lacking the right nutrient balance. Senior cats often benefit from vet diet cat food to support kidney function. Also, ensure they have easy access to hydration with a smart pet fountain that encourages more regular drinking.
7. Behavioural Changes
If your usually content kitty has become cranky, withdrawn, or more vocal, it could be due to discomfort, nutritional deficiencies, or underlying health conditions. A diet that supports overall wellbeing—including brain and nerve function—can make a real difference. Some science-based diets include added omega-3 fatty acids and antioxidants that help maintain cognitive health in ageing cats.
