Striving to meet your pet’s needs and ensuring their overall happiness and well-being is imperative and something you will be doing daily. It can be bothersome at times if your kitty seems to be eating non-stop, though. A relentless hunger in kittens can have you questioning if you are feeding them correctly, if their hunger is normal, or if there is an underlying issue to be investigated and concerned about.

The reason why your kitten is hungry all the time won’t be the same for all cats and will be on a case-by-case basis. Perhaps you aren’t feeding your cat the right food or amount for their individual nutritional needs, weight, and preferences. Alternatively, you may simply have a greedy pet on your hands, or there could be problematic medical or behavioral issues behind their ravenous appetite. Our top nine reasons below will help you discover more on this topic and reveal potential reasons behind their constant cravings.

The 9 Possible Reasons Your Kitty is Always Hungry

1. Growth and Development

Kittens are growing rapidly and forging through various stages. They need more calories and nutritional support to feed their development and may require more frequent meals during their early months.

2. Metabolism

Kittens generally have higher metabolic rates than adult cats. This increased metabolic activity can make them burn through calories faster, and therefore, feel hungry more often.

3. Activity Level

If your kitten is very active, athletic, and playful, they will burn more calories, leading to an increased appetite. If you have other cats or even dogs that they like to play with, this again may influence the amount of energy and calories used, which, in turn, is reflected in their appetite.

4. Feeding Schedule

Ensuring that you’re feeding your kitten an appropriate and balanced diet is only half of it. You’ll also need to make sure you’re feeding an adequate amount on a timely schedule. Kittens have tiny tummies so will do better with more frequent, small feedings rather than one big one once a day. If the feeding schedule or portion sizes are not adequate for your kitten’s weight, age, and breed, they may still feel hungry.

5. Parasites (Worms)

Parasites, such as roundworms or hookworms, are common in young kittens and can, depending on the load, increase a kitten’s appetite. This is because the parasites are using your kitten as their source of nutrition and energy, making it so your kitten gets less out of the food they eat.

Regular worming of your kitten is advised. Your veterinarian will be able to recommend a schedule and appropriate product to use, and they can also check for the current presence of any of these parasites.

6. Boredom or Attention Seeking

Sometimes, kittens may eat out of boredom or to seek attention. Ensure your kitten is mentally stimulated and engaged with toys, an enriched environment, and playtime. Seeking out the help of reputable cat specialists or behaviorists will help you too, as they are a great source of ideas and solutions to this problem and can shed some light on their behavior.

7. Dietary/Food Needs

The kitten food you are providing might not be satisfying or meeting their nutritional needs. Make sure you’re feeding a high-quality kitten food appropriate for their age, breed, and size.

They must be fed a complete feline diet and one that is manufactured for kittens, as they have different requirements than adult cats. Low-quality foods may not be as readily utilized as high quality ones, making it so that your kitten is not getting what they need from a poor quality diet.

8. Underlying Medical Conditions

Several illnesses and health issues can cause kittens to eat more or seemingly all the time. This can include illnesses that affect nutrient absorption or digestion, as well as issues that can affect how well a kitten can eat.

9. Medications

If your kitten is on medication, know that drugs can have side effects, and some can give kittens and cats an increased hunger. Check with your vet regarding any side effects of any medication you may be administering to your kitten to rule this out as the cause.

As you can see, your kitten may be eating a lot or act like they’re always hungry for many reasons, and it might be a process of elimination to find out the true cause of this. If you’re concerned about your kittens’ eating habits or if their voracious appetite is a persistent problem, it’s always a good idea to consult with your veterinarian. They can provide specific and tailored advice based on your kitten’s age, weight, and overall health. Regular veterinary check-ups are important to ensure your kitten is growing and developing properly and also provide you the opportunity to raise any concerns you may have.
