10 Signs Your Cat’s Diet Needs an Update for Better Health
Just like us humans, cats thrive on a balanced, nutritious diet that suits their age, health and lifestyle. But even the most paw-some meals can become less effective over time – or might not be the right match at all. If you’ve found yourself wondering whether your feline’s food is still the cat’s whiskers, you’re not alone. Let’s break down the signs your cat’s diet might need a change, and what you can do to keep them purring with good health.
Changes In Weight – Up Or Down
Unexpected weight gain or noticeable weight loss is often one of the clearest signs something’s up with your cat’s diet. If they’re gaining weight and don’t seem more or less active than usual, their current food may be too calorie-dense or nutrient-heavy. On the flip side, unexplained weight loss could suggest your cat isn’t getting the nutrients they need, or there could be an underlying health issue needing attention.
If you’re unsure, switching to a formula that supports weight management might help, along with a check-in at the vet for peace of mind.
Low Energy or Lethargy
Cats are known for their love of naps, but they should also have playful bursts of energy, especially if they’re young or in their prime adult years. If your kitty has lost their usual spark, their diet may be lacking essential nutrients, such as protein, B vitamins or fatty acids.
Consider feeding them a high-quality diet rich in protein, like options from Feline Natural or Orijen, or explore formulas developed for optimal vitality within science health nutrition.
Poor Coat Health Or Skin Issues
A cat’s coat is a mirror to their inner health. Dull fur, excessive shedding, dandruff or itchy skin can all be signals that your cat's diet might be missing key nutrients like omega-3 and omega-6 fatty acids, or even zinc.
Have a look at foods that support skin and coat health or consider adding supplements into their routine to top things up.
Digestive Upsets Like Vomiting Or Diarrhoea
While occasional hairball-related throw-ups can be normal, frequent vomiting, diarrhoea, or constipation are not. These are often signs that something in their diet isn’t sitting right. It could be an intolerance to certain ingredients or a need for more digestible formulas.
Foods targeting cat digestive health can help soothe sensitive tummies and support better nutrient absorption. If your cat has ongoing digestive challenges, consult your vet — they may recommend a specialised vet diet.
You're Noticing Selective Eating Or Food Refusal
Cats can be fussy eaters, but if your feline friend is suddenly turning their whiskers up at food they previously loved, it may be time to introduce something new. Cats can develop food aversions or get bored of the same flavours – particularly if they eat only dry or only wet food.
Try rotating trusted meals or adding food toppers to enhance appeal. You might also consider transitioning to rotational feeding with a cat food bundle that includes both wet and dry options for variety.
What To Do If You Need To Switch
If you're seeing one or more of these signs, don't worry — cats are resilient, and a few adjustments can often restore their health and happiness. To avoid shocking their sensitive systems, always transition to new food gradually over 7–10 days by mixing increasing amounts of the new food with their current one.
