Why Cats Eat Kittens: Discover 11 Real Reasons Why

I remember receiving a call from my mum telling me she had walked in on my cat eating two of her kittens. Saying I was shaken would be a vast understatement!

I did some extensive research to try and understand this behavior only to find out that it is completely normal!

The mother cat’s primary goal when eating her kittens is to protect her litter. A decaying body will attract predators and lead them to the other kittens. Sometimes, while cutting the umbilical, mama cat may get carried away and eat the kitten.

Why Do Cats Eat Kittens?

Why mother cats eat their kittens is something that puzzles most cat owners. Here are some common reasons why:

  • Stillborn kittens
  • Kitten has birth defects/deformed
  • To protect them from predators
  • Stress
  • Threatened
  • Kitten is malnourished
  • Mama cat is malnourished
  • Mama cat has mastitis
  • Mama cat can’t recognize her kittens.

1. Stillborn Kittens

Mama cat will eat any stillborn to protect her living kittens for two main reasons;

  1. Dead kittens are prey and will attract predators to where the other kittens are.
  2. A decomposing kitten will also pose a hygienic risk to the surviving litter.

Since a cat can only move one kitten at a time to safety, she will choose the easy way out which is to eat the dead kitten. This will clean up her nest to keep the predators away.

The queen may also eat her stillborn for nutrition. The dead kitten is a protein source and will help provide enough nutritious milk for her surviving litter.

2. Kitten Is Deformed

Cats will not rear deformed kittens. Some queens will choose to eliminate them to protect their species where only the strong survive.

As much as cannibalism seems gruesome, cats will eat their deformed kittens to protect them from the extensive suffering that will come along with birth defects. This explains why it is rare to come across a cat that is deformed.

Eating up a deformed kittie ensures that the feline generation continues without any weaknesses such as deformities.

Alternatively, the queen might choose to reject the deformed kitten. If this happens, you will notice that she does not nurse the kittie with birth defects and may choose to take the deformed kitty away from the rest of the litter. Gently take the secluded kitten and feed her. You can also take it to the vet for a checkup.

3. To Keep Off Predators

Cats will only let their kittens grow where they feel they are safe. Although this instinct is common to wild/outdoor cats, indoor cats will also not hesitate to do whatever it takes to protect their young ones.

To avoid such a scenario, you need to protect your cat and her litter from unfamiliar noises and pets. It is crucial for the cat if you give her time to give birth and nurse her kittens. Stay away from the room they are in and only go in when it is necessary. The queen will introduce the kittens to you with time whenever she is ready to do so. DO NOT pressure her!

4. Stress

Just like us, cats also undergo stress during maternity. If mama cat experiences too much pressure, pain and anxiety during her labour, all these may be too much for her, and she may end up eating her young ones.

Cats will also eat kittens when they sense some environmental stress. These include;

  • Excessive foot traffic in the room she is in
  • Loud noises
  • Over-handling, and manipulation of her kittens

All these may trigger some amount of stress and nervousness in the cat, and she might feel threatened.

When mama cat is stressed and nervous, she’ll start worrying about her kitties and their safety. She’ll begin worrying about predators getting to her, or you taking the kittens to predators and end up eating the kittens to protect them.

5. Mama Cat Feels Threatened

While in labour, nursing and taking care of her litter, the queen does not want to feel threatened. Mama cat will consider anything as a threat from other pets to humans.

It does not matter to her if, before her labour, she was comfortable with other pets and humans. All she cares about is the present and her maternal instincts feel threatened.

DO NOT attempt to move the kittens from where mama cat has placed them. You should respect her privacy and understand that she gave birth, where she feels comfortable.

If this happens, some cats will eat the kittens. You need to limit access to where she is and wait for her to introduce her kittens to you.

If you’re excited and a little impatient, you can gradually introduce the kittens to the household once they are in their weaning stage.

6. Kitten Is Malnourished

Cats eat kittens whenever they are malnourished. This is, however, more common in outdoor/wild/stray cats.

Mama cats instincts will tell her which kitten will not be able to survive, and she will choose to eat them.

7. Mama Cat Is Malnourished

If the mama cat is malnourished, she will gauge how many kittens she can comfortably nurse and eat the remainder.

The kittens she will eat will provide her with enough nutrients to enable her to breastfeed the remaining kittens.

Pregnancy requires the cat to feed on properly balanced meals to help her during and after her pregnancy.

To avoid this, you can consult with your vet during pregnancy to get proper feeding recommendations.

8. Mama Cat Has Mastitis

Mastitis is a painful condition where the queen feels pain while breastfeeding her kittens.

As a result of the immense pain the queen may be feeling, she might choose to either eat or completely ignore her kittens.

If you see any of these signs, it’s time to make a visit to the vet:

  • Mama cat doesn’t want to nurse/suckle her kittens.
  • Kittens not putting on enough weight
  • Some swelling on the mammary glands
  • Mama cat vomiting
  • Anorexia
  • Gangrene or abscesses
  • Bloody or pus discharge from mama cat’s mammary glands.
  • Fever

9. Mama Cat Does Not Recognize Her Kittens

Why do mother cats eat their kittens?

Sometimes the queen may not recognize her kittens, but this is mostly if she underwent a C-section.

The mama cat may not be able to know that the kittens came from her, and consequently, her body will not produce maternal hormones that bond queens with their litters.

Usually, mama cats eat kittens they do not recognize as their own.

Sometimes, first-time mothers may also confuse their kittens with prey and end up eating them.

Humans over-handling/manipulation of kittens may also make cats eat kittens. The different scents tend to confuse the mama cat, and she will not recognize her kittens as her own.
