Untamed tackles this common question and delves into the ins and outs of different types of cat food! You will also learn:

Can I feed my kitten cat food?

The answer to this question depends on what you consider to be adult cat food.

The following opinions prevail:

  1. Solids
  2. Commercial cat food specifically formulated for adult catsĀ 

Can kittens eat solids?

Kittens shouldnā€™t eat solids until they start weaning, which is usually between weeks five and eight.Ā 

Look for the following signs to know your kitten is ready to try solid food:

  • Focused vision
  • Good mobility (standing on all fours with erect tail)
  • Increased curiosity and playfulness
  • First teeth (incisors and canines)

Once your kitten is ready to switch to solids, you can start mixing wet or dry cat food with some kitten milk replacer (KMR) or water. For the next 3ā€“5 weeks, you should gradually reduce the liquid in the food until your furry friend switches to solid meals only.

Can kittens eat commercial cat food formulated for adult cats?

Kittens can eat commercial food for adult cats as long as it contains all essential nutrients necessary for a healthy feline diet. But, what about treats for adult cats?

After kittens wean off milk, they can enjoy an occasional treat or two, but keep in mind that treats are not substitutes for meals, especially not for a growing kitten. Even fully developed cats shouldnā€™t have snacks frequently because the calorie surplus can lead to obesity or various eating disorders.

Why is my kitten so drawn to adult cat food?

Kittens often crave adult cat food because of:

  • Teethingā€”If you left cat biscuits for your older furry friend, a kitten might chew on them during the teething phase because they are hard and tasty
  • Tempting smellā€”Some manufacturers spice up their food with artificial flavours your curious kitten canā€™t ignore
  • Mimicking their motherā€”Kittens look up to their mother, so when they see her munch on food and leave some in the bowl, they'll want to have a taste

Whatā€™s the fuss around kittens and adult cat food?

Many experts claim that kittens need more nutrients and calories than adult cats because they are growing and developing rapidly.

The only difference between food for kittens and adult cats is that the former typically contains more calories than the latter. You can feed your kitten adult cat food as long as:

  • Your kitten is ready to eat solids
  • The food is nutritionally complete
  • You portion the meals properly

How to choose good cat food

If youā€™re new to cat parenting, choosing cat food might seem perplexing, so this short guide to what cats eat will help you pick the best products.

What are the options?

Once your kitten is ready to eat solids, you'll have the following options to choose from:

  • Dry foodā€”Typically the most affordable product and the favourite of many cats. If nutritionally adequate, cat biscuits are a great option for kittens but must be moistened with KMR, chicken soup, or broth to compensate for the lack of moisture. Avoid milk (even lactose-free products) as it causes stomach disturbance in cats
  • Wet foodā€”Richer in protein than dry food and easier to chew and swallow, itā€™s the closest thing to a natural feline diet in texture and moisture content. You can mix it with tiny amounts of KMR to make the transition smoother
  • A mix of wet and dry foodā€”The best option nutrition- and budget-wise. It ensures your kitty gets the benefits of both food types. You can mix them or serve them as separate meals throughout the day
  • Semi-moist foodā€”Despite its convenience, semi-moist food is often packed with sodium, sugar, grains, undefined meat sources, and artificial colouring and flavouring
  • Homemade foodā€”If you have the time to research recipes, consult with your vet, and cook for your kitten, an occasional homemade meal can be a delicious treat

How to prevent your kitten from stealing your adult catā€™s food

Adult cat food is not dangerous for kittens, but they shouldn't eat as much as they want. If you have more than one cat, it's also vital to teach them to respect their siblings' food.

Here are some tips on keeping your cats disciplined and well-mannered:

  • Establishing separate feeding schedules
  • Setting up feeding areas in different rooms
  • Monitoring your feline companions during mealtime

More cat parenting basics

We created a practical guide to help first-time cat parents take care of their furry friends. You can learn about:

  • Weight tracking
  • Ways to motivate a stubborn weaner to eat
  • How to switch your kitten from one type of food to another
  • Signs warning you to visit the vet
  • Foods to avoid

Kitten weight chart

The best way to monitor your kittenā€™s growth is to keep track of their weight.

The following table shows approximate weight ranges and recommended daily food intake for your kittenā€™s first weeks:

Weeks

Approximate weight

Recommended daily intake (for formula)

One

50ā€“150 grams

30 ml

Two

150ā€“250 grams

60 ml

Three

250ā€“350 grams

90 ml

Four

350ā€“450 grams

120 ml

Five

450ā€“550 grams

150 ml

Six to nine

550ā€“850 grams

180ā€“270 ml (less if mixed with solid food)

Should your kitten start losing weight, you must notify your veterinarian immediately since weight loss in kittens can be a symptom of the fading kitten syndrome (FKS), often fatal but curable if discovered early.

Handling stubborn weaners

Sometimes, kittens have a hard time separating from their mums or adjusting to new tastes. If your kitten is struggling with weaning and rejecting wet food, donā€™t be discouraged!

The following methods can help you get your kitten used to solids:

  • Start off smallā€”Add a teaspoon of solid food into KMR and increase the amount every two days
  • Serve the mixture in a shallow dishā€”Your kitten might have a hard time reaching the food if youā€™re serving it in a deep bowl. When eating from a shallow plate, theyā€™re less likely to make a mess
  • Dip your finger into the mixture and gently rub it around your kittenā€™s mouthā€”Scaredy cats need some encouraging but handle your kitten with care to avoid hurting them

Switching foods? Not a problem!

Your kitten got used to one type of food and now refuses to switch to another?

Hereā€™s how to sneak new food into your catā€™s diet without them noticing:

  1. Get your catā€™s current favourite food and the new brand you want to introduce
  2. Mix 90% of the old product with 10% of new food
  3. Mix 10% more every day until the new product has no traces of the old one

If your cat starts getting suspicious, reduce the amount of new food and slow down the process. In case your feline needs additional motivation, you can always:

  • Add a dash of soup, broth, homemade gravy, or special pet food spices to your catā€™s food
  • Warm up the meal before serving
  • Try moving the dish around the house to see which spot works best

When to rush to the vet

Kittens are fragile creatures. What would be a mild issue for a cat could be life-threatening for your kittenā€™s sensitive organism.Ā 

If you notice any of the following symptoms(especially after giving new food to your kitten), you should take your furry companion to the vet immediately:

A quick reaction could increase the chances of your kittenā€™s recovery and potentially prevent a lethal outcome.

Busting famous cat food-related myths

With an abundance of info on cat food available, you can come across preposterous claims.Ā 

Here are some popular myths related to cat food and the truth behind them:

  1. High-protein cat food is always goodā€”You should strive to feed your kitten a high-protein diet only if the protein is sourced from animals. As obligate carnivores, cats lack the enzymes necessary to break down and absorb plant protein, so vegan cat food should be off the table
  2. All organic and all-natural products are goodā€”These labels can be deceiving if you donā€™t check the ingredient list. Organic and all-natural means nothing if the food doesnā€™t contain enough meat
  3. All meat derivatives are wasteā€”The term is vague, so you can't know whether the manufacturer uses real meat or hooves, beaks, and other slaughterhouse scraps. Even though meat derivatives donā€™t have to be junk, stick to products with clearly stated meat source to be on the safe side
  4. Raw food is better for catsā€”Wild cats thrive on raw meat because they eat fresh prey. Raw meat we give to domesticated cats has been refrigerated and can be full of bacteria and other parasites. Improper preparation and storage of raw meat (the most popular option being chicken) can lead to contamination with E. coli, Listeria, and Salmonella. Raw bones are another major concern as they can cause internal and external injuries
