Dry food for older cats
Dry food for older cats is usually lower in calories than an adult recipe, since ageing cats are typically less active, and often carries added support for joints or a formula that is gentler on kidneys. "Senior" is not a strictly regulated term, so the important part is what a specific bag actually contains rather than the word on the front.
What changes as a cat ages
Most cats become less active from around seven or eight years old, so a food with the same calorie density as an adult recipe can lead to gradual weight gain even without a change in appetite. Senior formulas are usually adjusted downward in calories for exactly this reason.
Kidney function also tends to decline gently with age in cats, which is why many senior recipes are formulated with controlled phosphorus levels, and dental wear or tooth loss can make some older cats prefer a smaller or softer kibble shape.
What the label words actually mean
"Senior" or "7+" on a bag is a marketing description, not a regulated life-stage category the way "complete" is, so two senior foods from different brands can differ a fair amount in calorie content and what they emphasise. Reading the guaranteed analysis and ingredients rather than trusting the word senior alone tells you more.
Look for a stated calorie count you can compare against your cat's current food, and check whether the recipe highlights joint support, kidney-friendly protein levels, or simply a lower-fat formula, since these solve different problems and your cat may need one more than another.
Switching an older cat's food
Older cats can be more particular about a food change than younger ones, and a sudden switch is more likely to unsettle digestion in a senior cat. Mix the new food in gradually over a week or two rather than swapping bowls outright.
If your cat has a diagnosed condition such as kidney disease, any change in food should go through the vet managing that condition rather than being chosen off a bag alone, since a therapeutic diet prescribed for a specific illness is a different thing to a general senior formula.
Dry, wet, or both
Dry food keeps well, is easy to leave down for a cat that grazes through the day, and tends to be cheaper per meal than wet food, which suits an owner managing several cats or a cat with steady, predictable eating habits.
Some older cats do better with at least some wet food added in, particularly if they drink less than they should or have started to lose interest in dry kibble as their sense of smell or dental comfort changes with age. There is no rule that says an older cat must be on one format or the other — plenty do well on a mix of both, and switching entirely is only worth doing if your cat's own eating habits are pointing you that way.

Common questions
- At what age is a cat considered senior?
- Most senior cat foods are aimed at cats from around seven years old, though the exact age varies by brand and there is no official cut-off. It is more useful to watch your own cat's activity level and weight than to switch food purely because of a birthday.
- Do older cats need lower-calorie food?
- Often yes, because most cats become less active with age and can gain weight on the same food that suited them as a younger, more active cat. A senior recipe formulated with fewer calories can help, but weigh your cat regularly and adjust portions rather than relying on the food alone.
- Should I switch my older cat to wet food instead of dry?
- Some older cats manage wet food more easily if they have dental wear or drink less than they should, since it adds moisture and is softer to chew. Others do perfectly well on dry food throughout their lives. Either can work; what matters is that your cat eats it consistently and comfortably.
- My older cat has lost weight — should I switch food?
- Unexplained weight loss in an older cat is worth a vet visit before changing food, since it can be a sign of several conditions that need diagnosing rather than managing with a different bag from the shelf. A vet can advise on the right food once the cause is known.
