Choosing Cat Food: A Practical Guide for Kittens, Adult Cats and Special Needs

A bag of cat food with an attractive picture and words like “premium” doesn’t necessarily tell you whether it’s right for your cat. The right choice depends on age, activity level, health condition, taste preference, and whether it’s a complete meal or a supplement.

Many cat owners in the UK come up against the same pitfalls:

  • A flavour name is mistaken for a high meat content. “Chicken” or “tuna” on the front doesn’t automatically mean that ingredient makes up the largest part of the recipe. Check the ingredients list and the stated percentage.
  • “Grain-free” is seen as essential for every cat. Grain-free cat food can suit a specific dietary choice, but it isn’t necessary for every cat. A recipe without grains isn’t automatically more digestible either.
  • Wet food, soups and treats are used as a complete meal. Always check whether the packaging says “complete” or “complementary”. Felix Soup Fish, for example, is a complementary cat food and is intended to be given alongside a complete diet, not as the sole daily meal.

The Key Points on the Label

1. Check Age and Life Stage

A kitten has different nutritional needs to an adult cat. Kitten food is typically tailored to the growth phase and includes guidelines for different ages and weights. Purina One Junior Chicken & Grain Formula is, according to the product information, intended from weaning up to 12 months and is described as a complete food for kittens.

For cats from around one year old, look for cat food for adult cats. The recommended amount then depends on weight, activity and body condition. An indoor cat with little exercise may need less than an active outdoor cat.

After spaying or neutering, an adjusted energy intake may be relevant. Purina One Sterilcat Beef & Grain Formula is, according to the product description, intended for spayed or neutered adult cats, with a stated protein-to-fat ratio and adjusted minerals. Check the feeding table and adjust the amount when your cat’s weight changes.

2. Choose Between Wet Food, Dry Food or a Combination

Wet cat food contains plenty of moisture and is available in mousse, sauce, jelly and chunks. It’s handy for cats that like to eat small portions. Pay attention to storage instructions: opened portions usually need to be covered and kept in the fridge, and used within the time stated on the packaging.

Dry cat food is easy to portion and practical when you’re not at home during the day. Seal the bag properly and store the food in a cool, dry place. A product like Purina One Urinary Care Chicken is a complete dry food for adult cats, with a stated composition including 34% crude protein and 14% fat.

A combination of wet and dry food can work, but add the daily amounts together. Use the guidelines on both packs as a starting point and avoid treats unknowingly making up a large part of the energy intake.

3. Look Beyond Marketing Claims

A term like “for sensitive stomachs” describes an intended use, but doesn’t replace a diagnosis. If your cat is persistently vomiting, has diarrhoea, is in pain, drinking a lot or showing changes in urination, it’s wise to contact a vet. Introduce new food gradually, for example over about seven days, so you can see how your cat reacts.

With cat food for sensitive stomachs, you can look for a straightforward ingredients list, a clear feeding guideline and a complete composition. Purina One Sensitive Adult Turkey & Rice lists turkey as the first ingredient and states no added wheat. The claim about a possible change in stool odour is based on Purina’s own research; so don’t regard this as a guaranteed result for every cat.

The same applies to urinary cat food: a product for urinary tract support is not a treatment for bladder crystals or a urinary tract condition. If your cat is struggling to urinate or is urinating unusually often, first seek advice from a vet.

Frequently Asked Questions About Cat Food

Which cat food is suitable for a kitten?

Choose food that clearly states it is for kittens and the relevant age stage. Kitten food contains feeding guidelines based on age and weight. Don’t switch to adult cat food without reason; follow the instructions on the packaging.

Is wet food or dry food better for cats?

Both types can work when they are complete and correctly portioned. Wet food provides relatively high moisture per portion, while dry food is easy to store and weigh out. A combination can also work, as long as you monitor the total daily amount.

How long can you store opened cat food?

Dry food remains usable according to the date and storage instructions on the packaging, provided the bag is kept well sealed and dry. Opened wet food should be covered and kept in the fridge. Always check the label; some products state a maximum of 24 hours and others up to two days. Serving temperature and hygiene also affect how well your cat accepts it.
