Cats are masters at hiding their age. They will groom themselves, carry on with their routines, and appear perfectly fine — right up until the point where a health issue has quietly been developing for months. One of the most powerful things you can do for an aging cat is get their nutrition right. Senior cat food is formulated specifically for the changes happening in your cat’s body — and choosing the right one can add healthy comfortable years to their life.
In this guide we cover the best senior cat foods available in Australia, what to look for on the label, and how to transition your cat without the drama.

What Changes in a Cat’s Body as They Age?
Understanding why senior cat food is different helps you choose better:
- Reduced kidney function — the most common senior cat health issue. Kidneys struggle to filter waste, making protein quality critical.
- Slower metabolism — calories need adjusting to prevent obesity or unhealthy weight loss.
- Reduced digestion efficiency — senior cats absorb nutrients less effectively, requiring more digestible food.
- Joint stiffness — just like dogs, senior cats benefit from foods containing glucosamine and omega-3s.
- Dental sensitivity — many senior cats develop dental issues that make hard kibble painful.
- Reduced thirst sensation — senior cats are at higher risk of dehydration, making wet food particularly important.
Wet Food vs Dry Food for Senior Cats
For senior cats wet food is generally the better choice — or at minimum a mix of both. Wet food provides hydration which is crucial for kidney health in senior cats. It is easier to eat for cats with dental pain. It is higher in protein relative to carbohydrates. And it is more palatable for cats with a reduced appetite. If your cat is firmly attached to dry food, look for a high quality senior kibble and add a little water or low-sodium broth to increase their fluid intake.

The Best Feeding Approach for Senior Cats
The most effective feeding strategy for most senior cats is to combine both wet and dry food. Feed the Hill’s Science Diet wet pouches once or twice a day for hydration and palatability, and leave a small amount of the Hill’s 11+ dry kibble available for grazing. This combination ensures your senior cat gets adequate moisture, complete nutrition, and something to snack on between meals — which many senior cats prefer over two large meals.
How to Transition Your Cat to Senior Food
Cats are notorious for refusing new food — especially older cats set in their ways. A gradual transition over 7 to 10 days is essential:
- Days 1–3: 75% old food, 25% new food
- Days 4–6: 50% old food, 50% new food
- Days 7–9: 25% old food, 75% new food
- Day 10+: 100% new food
If your cat refuses at any stage, slow down. Some cats need a 2 to 3 week transition. Warming wet food slightly can help increase palatability during the switch.
Frequently Asked Questions
When should I switch my cat to senior food?
Most cats benefit from a senior diet from age 7 onwards. If your cat is showing signs of aging earlier — weight changes, reduced activity, dental issues — discuss an earlier switch with your vet.
Is kidney disease common in senior cats?
Very — chronic kidney disease affects around 30 to 40 percent of cats over 10 years old. A kidney-supportive diet with controlled phosphorus is often recommended. If your senior cat has been diagnosed, ask your vet about prescription kidney diets.
How much should I feed my senior cat?
Follow the feeding guidelines on the packaging as a starting point, adjusted for your cat’s weight and activity level. Senior cats who are less active often need slightly less than the packaging suggests. Your vet can give you a precise recommendation.
Our Verdict
For most senior cats the combination of Hill’s Science Diet 7+ wet pouches and Hill’s 11+ dry kibble is the gold standard — trusted by vets, clinically proven, and available on Amazon Australia with fast delivery. Start with the wet pouches and introduce the dry food gradually for the best results.
