Wet food is one of the most important dietary choices you can make for a senior cat. As cats age their kidneys become less efficient, their sense of thirst diminishes, and their ability to stay adequately hydrated from dry food alone becomes increasingly compromised. Wet food addresses all of these challenges simultaneously — providing the moisture content that supports kidney health, the palatability that tempts cats with reduced appetite, and the softer texture that accommodates cats with dental sensitivity or missing teeth.

Why Wet Food Is Particularly Important for Senior Cats
- Kidney support — wet food provides 70 to 80% moisture versus 10% in dry food — critical for aging kidneys
- Encourages eating — stronger aroma and softer texture appeal to cats with reduced appetite or dental pain
- Higher protein density — supports muscle maintenance in aging cats
- Easier to digest — gentler on aging digestive systems
- Weight management — lower calorie density than dry food helps manage senior cat weight

How Much Wet Food Does a Senior Cat Need?
A typical senior cat needs approximately 200 to 250 calories per day depending on their size and activity level. An 85g pouch of Hill’s Science Diet 7+ contains approximately 65 to 75 calories — meaning most senior cats need 3 pouches per day for their complete nutrition, or 2 pouches alongside a measured amount of senior dry food. Always follow the feeding guidelines on the packaging and adjust based on your cat’s body condition — you should be able to feel but not prominently see your cat’s ribs.
Transitioning Your Senior Cat to Wet Food
Senior cats who have eaten dry food their entire lives can be resistant to wet food. Transition gradually over 7 to 14 days — mixing increasing amounts of wet food with the familiar dry food. Warm wet food slightly to increase aroma — this is particularly effective for cats with reduced smell sensitivity. Try different flavours if your cat rejects one — chicken, fish, and turkey all appeal to different cats. If your cat remains completely resistant try adding a small amount of wet food as a topper over their dry food rather than replacing it entirely.
Frequently Asked Questions
Can I feed my senior cat wet food only?
Yes — a complete and balanced wet food like Hill’s Science Diet 7+ can be fed as your cat’s sole diet. Ensure you are providing enough pouches to meet their daily calorie needs and provide fresh water alongside even wet-food-only diets.
My senior cat has kidney disease — is wet food especially important?
Yes — wet food is strongly recommended for cats with kidney disease. Increased water intake from wet food helps dilute urine and reduce the workload on compromised kidneys. Many vets specifically recommend switching kidney cats to wet food as one of the most impactful dietary changes available.
Our Verdict
For Australian senior cat owners, Hill’s Science Diet Adult 7+ wet pouches are the gold standard recommendation — vet formulated, kidney-supporting, highly palatable, and conveniently packaged for daily use. If there is one dietary upgrade you make for your senior cat this year, switching to or adding a quality wet food like this is the most impactful choice you can make.
