6 Signs It's Time to Change Your Cat's Kibble
Most cats are creatures of habit—but that doesn't mean they'll want to eat the same food forever.
As your cat grows, their nutritional needs change. They may also develop new preferences, become less active, or simply stop enjoying the food they've always eaten.
Knowing when it's time to switch to a new kibble can help keep your cat healthy, happy, and excited about every meal.
1. Your cat has lost interest in their food
Does your cat sniff the bowl and walk away? Or eat much more slowly than usual?
A sudden lack of enthusiasm doesn't always mean they're being fussy. Cats have individual food preferences, and they can become less interested in the same recipe over time.
If your cat is otherwise healthy, trying a new flavour or a different source of animal protein may be enough to bring back their appetite.
2. Their coat has become dull
Your cat's coat often reflects what's happening on the inside.
If their fur looks dry, lacks shine, or they're shedding more than usual, it may be worth reviewing their diet.
Recipes rich in quality animal protein and essential fatty acids, including omega-3 and omega-6, help support healthy skin and a soft, glossy coat. Adding wet food alongside kibble can also increase moisture intake and contribute to overall wellbeing.
3. They've been spayed or neutered
After neutering or spaying, your cat's metabolism naturally slows down.
Many cats become less active while their appetite stays the same, making weight gain more likely.
A recipe specifically formulated for neutered cats can help maintain a healthy body condition by providing balanced nutrition that's appropriate for their changing energy needs.
4. Your cat is gaining weight
If your cat is becoming less lean despite eating normal portions, their food may no longer be the best match for their lifestyle.
Indoor cats, in particular, often burn fewer calories than outdoor cats.
Choosing a balanced recipe with appropriate calorie levels and high-quality protein can help support healthy weight management while keeping your cat satisfied.
If you're concerned about your cat's weight, your veterinarian can recommend the most suitable feeding plan.
5. Your kitten is becoming an adult
Kittens need extra energy and nutrients to support rapid growth and development.
Around 12 months of age, most cats are ready to transition from kitten food to an adult recipe. Large breeds such as the Maine Coon mature more slowly and may benefit from kitten food until 18–24 months.
Switching at the right time helps provide nutrition that's better suited to your cat's current stage of life.
6. Your cat is entering their senior years
As cats get older, their nutritional needs change once again.
Many cats are considered seniors from around 7 years of age, although this varies between individuals.
Senior formulas are designed to support healthy ageing with highly digestible ingredients and nutrients that help maintain mobility, immune function, and overall vitality.
If your cat is slowing down or entering a new life stage, it may be the right time to review their diet.
How do you switch to a new kibble?
A gradual transition is always the best approach.
Changing food too quickly can upset your cat's digestive system and may lead to vomiting, diarrhoea, or refusal to eat.
A simple 10-day transition works well for most cats:
- Days 1–3: 75% current kibble, 25% new kibble
- Days 4–6: 50% current kibble, 50% new kibble
- Days 7–9: 25% current kibble, 75% new kibble
- Day 10: 100% new kibble
Every cat is different. If your cat adapts comfortably, you can continue as planned. If they seem sensitive to the change, simply slow the transition down and give them a little more time.
Choosing a complete, high-quality recipe made with carefully selected ingredients helps make every change easier—and every meal more enjoyable.
Frequently Asked Questions
Should I change my cat's kibble?
Sometimes, yes. Changes in age, activity level, body weight, or food preferences can all be good reasons to switch to a more suitable recipe. Any transition should always be gradual.
Should I change my cat's food if they vomit?
Occasional vomiting isn't always caused by food. Hairballs, eating too quickly, or an empty stomach are common reasons. However, if your cat vomits frequently after meals, consult your veterinarian to rule out any medical problems before changing their diet.
How do I change my cat's food if they have diarrhoea?
If your cat has diarrhoea, speak with your veterinarian first to identify the cause. If a diet change is recommended, introduce the new food more slowly than usual—over two to three weeks—and monitor your cat's progress carefully.
When should I switch my kitten to adult food?
Most cats can move to adult food at around 12 months of age. Large breeds, such as Maine Coons, may benefit from staying on kitten food until they are between 18 and 24 months old, as they mature more slowly.
