Choosing the Right Food for an Older Cat

In this guide

It is easy to keep picturing your cat as the feisty kitten you first brought home. Cats do not show the visible signs of ageing the way people do, but looking young on the outside does not mean a cat's body still functions the way it did as a youngster.

As a cat's body changes with age, so do its nutritional requirements, and it falls to owners to make sure that need is properly met. This piece looks at how a cat's nutritional needs shift over time, what to look for when shopping for senior cat food, and offers a rundown of well-regarded options.

How nutritional needs change with age

There is no single formula that suits every life stage. Kittens need considerably more protein, fat and calories than adult cats because they are growing, while adult cats' main priority becomes maintaining a healthy weight.

According to the Feline Nutrition Foundation, a cat's energy requirements typically fall during middle age, roughly between four and nine years old, which raises the risk of weight gain during this period. Once a cat reaches ten to twelve years of age, however, energy requirements can rise again, and without a corresponding increase in calories, the cat risks losing muscle mass and becoming too thin. The scientific evidence here is still fairly limited, but one thing is clear: adequate protein remains essential throughout a cat's life. The best approach is a protein-rich diet with calorie intake adjusted as needed to keep body weight in a healthy range.

What to look for in senior cat food

Protein remains just as important for older cats as for younger ones, since cats are obligate carnivores and rely on animal-based protein for the bulk of their diet. Beyond protein, a few other qualities are worth prioritising in a senior formula:

• All-natural ingredients, since natural ingredients tend to be more digestible than fillers and by-products, aiding nutrient absorption
• Higher levels of taurine, an essential amino acid important for heart health that is particularly valuable for older cats and is found in animal proteins such as chicken, lamb and fish
• Lower fat and calorie content, since most cats become less active as they age and burn fewer calories, though weight and condition should still be monitored with a vet's guidance
• Higher moisture content, since many older cats develop dental problems that make dry kibble harder to chew, and the added moisture in wet food also supports digestion and kidney health
• Support for healthy weight, since while some older cats gain weight as they slow down, many others struggle to keep weight on, so the right formula depends on the individual cat

Choosing a food formulated specifically for older cats is the simplest route to meeting a senior cat's needs, though it is not strictly essential, provided whatever you choose delivers the right balance of protein, fat, calories and essential nutrients. The following recipes are worth considering:

1. Blue Buffalo Healthy Aging Chicken & Brown Rice Recipe, formulated to support immunity, heart health and digestion, featuring Blue Buffalo's LifeSource Bits, which are loaded with vitamins, minerals and antioxidants.

13. Blue Buffalo Natural Veterinary Diet K+M, formulated to support kidney health and mobility, two issues that are especially common in senior cats.

Whatever you choose, resist the urge to switch your senior cat's diet too quickly. A sudden change of food can upset a cat's stomach, so it is best to transition gradually over seven to ten days, starting by mixing around 25 per cent new food into the existing diet and slowly increasing the proportion as your cat tolerates it.
