Feeding Your Adult Cat

Once your cat has reached their first birthday, it’s time to think about a regular cat-feeding routine. As they change from a playful kitten to a full-grown adult cat, it’s important to make sure they have all the right nutrients they need to stay happy and healthy.

Getting to know your options

It might seem like there’s a huge amount of choice out there, and you’ll be asking yourself, “What is the best food for cats?” The good news is that whatever your cat’s lifestyle, condition or age, there’s a food that’s right for them.

Ultimately, unless influenced by a medical condition, deciding whether to give your cat wet or dry cat food is completely up to you (and your cat, of course!)

  • Dry complete diets are easy to measure and use, and have a longer shelf-life once opened than wet foods.
  • They also help to keep your cat’s teeth healthy. You can expect your cat to chew dry food more actively and take longer to eat.
  • Cats prefer to crunch their dry food and generally don’t like it soaked with water.

  • Some cats simply prefer the smell and texture of wet food. Wet food can still be very convenient with single-serve pouches and trays, giving your cat a fresh, easy-to-serve meal each time.
  • Your cat will also eat more in one sitting, and will drink less.

Some owners serve a mixture of dry and wet foods - some cats prefer wet food in the morning and dry food left out during the day to graze on. Try your cat with both to see which they prefer.

Range of adult cat foods

Purina produces many of the world’s leading dry and wet adult cat foods, for every life stage and lifestyle. See the full range here.

  • If your cat spends most of their time indoors, they may benefit from a special indoor formula to reduce hairballs, or a lower calorie diet, as they’ll be less likely to roam and more likely to put on weight.
  • If your cat is neutered, they may find a specialist food for neutered cats, that maintains a healthy urinary tract, helpful.
  • Older cats will also need to have a slightly adjusted diet, as well as pregnant mothers and cats that are obese or overweight

If your cat has special nutritional needs, or you are concerned about their diet, make an appointment to chat this over with your vet.

How to feed your cat

Cats are creatures of habit. So getting into a regular routine as soon as they’re ready to move onto adult cat food is best for both you and your cat.

Your cat’s designed to eat little and often – if you can feed them several small meals a day, great! However, if you’re feeding them wet food or your lifestyle doesn’t allow for this, then two meals a day is fine for most cats.

  • Feeding a cat in the same place and at the same time each day is best, in a quiet area where they can relax, well away from their litter tray.
  • Choose a surface that can be easily cleaned, or use a cat feeding mat, and always use a clean ceramic or metal bowl. Some cats may prefer to eat from a flat bowl or saucer – this can also help slow down fast eaters!
  • If you have more than one cat, make sure their feeding bowls are a reasonable distance apart to avoid any confrontation. If your cats really don’t get along, you may even need to have completely separate feeding areas to keep the peace.

When it comes to cat feeding, try to serve wet food (cans/tubs/pouches) at room temperature, as it smells more attractive and is easier to digest. This means taking it out of the fridge an hour or so before feeding. It’s fine to use the microwave for a short time to warm it through. But make sure that the food is never hot.

Wet food goes stale quickly. So avoid leaving it out. Once opened, don’t store wet food for longer than 24 hours, even in the fridge.

Dry food, on the other hand, can be left out during the day without spoiling. Store it in a clean, dry environment, ideally in an airtight container or a resealable box, to keep it tasty and maintain its aromas.

How much depends on your cat’s breed, lifestyle and body condition. Every cat is different. The most important consideration when feeding cats is to give them enough to maintain their healthy, lean body condition. Pet Lifestyle Guide

If you’re not sure how much to feed your cat, check the packaging for advice, or contact the Purina Pet Care Team.

An easy way to check your cat’s body condition for yourself is to simply run your hands around their sides and tummy. At an ideal weight you should be able to feel, but not see, their ribs quite easily, without a heavy covering of fat. If you look at them from above, their waistline behind the ribs should be clearly visible, with no folds at the sides when they walk.

If you feel your cat may be overweight or obese, you should contact your vet to work out a diet and lifestyle plan to help them return to a healthy weight.

If you think your cat needs to lose weight, and your vet agrees, you will need to take steps to help them whilst still giving them those all-important nutrients. If you have more than one cat, feed your overweight cat separately to avoid food stealing. Dividing your cat’s daily food into smaller, more frequent meals can help with weight control, but keep track of what and how much you’re feeding them.

It’s not all about diet – lifestyle is just as important when helping to manage your cat’s weight. If you’ve got an indoor or lazy cat, try introducing toys that encourage running around and being active to burn calories, like ‘fishing’ toys.

If you’re concerned about your cat’s weight, you could consider moving them onto special ‘light’ cat food, which are formulated with less calories so you don’t need to cut down on the actual amount of food you give your cat. The only thing reduced in these formulas is the calories, so they still get all the vitamins and minerals they need. Some of the light formulas created by Purina can help.

Weight loss should be slow and steady – rapid weight loss can be dangerous for your cat. The change could take months. So be patient!

Remember, your vet might suggest reducing the amount you’re feeding your cat, or switching to a special, low-calorie food, but never ‘starve’ your cat or restrict food without express advice from your vet.

Use our Body Conditioning Tool regularly, and continue the diet until an ideal body condition and weight is reached.

If your cat turns their nose up at their food, you’re not alone! Many cats have favourite textures and flavours, and can go off their food if anything changes. If your cat suddenly goes off their food or refuses to eat, make an appointment with your vet, as it could be a sign of an underlying problem. You can encourage a fussy cat to eat by:

  • Switching feeding time until after the rest of the household has eaten, and feeding in a quiet area away from noise and stress. You can also try changing from wet to dry food, or use a different flavour.
  • Make sure their bowl is clean – old food can be off-putting for cats. Try using a flat bowl or saucer.
  • Dry food absorbs moisture and becomes stale, especially in warm weather. Try replacing your supply if they usually eat dry food.
  • Serve wet food at room temperature, as it smells more attractive. Microwave wet food for a short time until it’s warm (never hot) to the touch.
  • Cats who roam outside can catch an unscheduled snack or two – they may just not be hungry. This is especially true in hot summer weather.

  • Complete ‘main meal’ diets don’t need any supplements to give your cat all the nutrients they need, but some foods, like treats, snacks and some purely meat/fish-based foods, aren’t nutritionally balanced on their own. Treats or snacks are fine in moderation, but reduce their main meals slightly if you do give them treats to avoid overfeeding! As a rule, no more than 15% of your cat’s daily calories should come from treats.
  • Home cooked treats like fresh meat or fish should be thoroughly cooked, with no salt added and all the skin and bones removed. For specially formulated cat treats, read the feeding guide on the packet for guidance on how to serve and how often.
  • If your cat is on a special diet advised by your vet, for weight loss or another medical condition, treats may be a no-no. Ask your vet what you can and can’t feed to be on the safe side.

Making sure your pet stays hydrated is just as important as feeding them the right cat food for their condition – this is especially true if you’re feeding cats dry food.

  • Make sure your cat has access to clean fresh water at all times – try putting a large, clean bowl of water in places you know your cat likes to relax in. Avoid putting your cat’s food and drinking water in the same place.
  • If your cat seems a bit put off their water, try a bigger bowl. Some cats really don’t like their whiskers touching the sides!
  • Cats don’t need milk after weaning, so don’t use milk as a water substitute. In fact, cats can be intolerant to the sugars in milk, and this can cause diarrhea if included in cat diets. Even specially-formulated ‘cat milk’ should be treated as a food or treat, not a drink.

We know it can be tempting to hand feed your cat tidbits – for a lot of people, it’s a sign of affection and shows how much you love your cat. However, human foods are often high in calories, and lack the essential nutrients that food for cats contains, so you could upset the balance of your cat's diet if you give them table scraps. Feeding a cat anything containing onion or onion compounds can also be harmful, so it’s better to be safe than sorry.

How to change your cat’s food

Changes in circumstances can mean that your cat needs adjustments to their diet. Even moving from a house with a garden to one without can mean your cat needs fewer calories as they won’t be running about as much! You should keep a careful eye on your cat’s eating habits and body condition, and if you spot any changes, or think that they may need a different diet, make an appointment to talk it over with your vet.

If your vet agrees that your pet needs a change in diet, then you’ll need to change it gradually to avoid upsetting their stomach with a sudden swap, whether it’s switching from wet to dry cat food, or between brands.

  • Put a little of the new food in with your cat’s current food and mix it all together.
  • Over the next week, gradually increase the amount of new food in the mix you give your cat, while reducing the amount of the old food. Some cats might need up to two weeks to change from one to the other completely. So be patient!
  • If you need to change your cat's diet but they’re currently unwell, ask your vet to advise on the best way and best time to make the change.
  • If you’re switching from wet food to dry food, your cat will need more water available to them throughout the day, and they might start to eat their food in more than one sitting, rather than eating it all at once.
  • If you’re switching from dry to wet cat food, it’s completely normal for your cat to drink a little less than usual, and eat more food in less time than they usually do.
  • Dry foods are usually more energy-dense than wet foods, so you may need to give your cat proportionally more wet food to get the same amount of calories.
