Having newborn kittens at home is surely a joyous sight for a cat owner. After waiting for your kitty’s babies, you finally welcome these new members to the family. But, with much horror, you discover that the mother cat devoured some of the kittens. Why do cats eat their babies? Let’s find out the answers and what you can do to save the kittens.  

Why Do Cats Eat Their Babies? 

Finding out that the kittens were eaten by their mother is both sad and terrifying. It also seems unbelievable, but do cats eat their babies? Unfortunately, the answer is yes. Although it happens rarely, it is normal in cats. It’s an instinctual reaction to certain situations that may not be favorable to the cat or its young. It can be an act of love, aggression, or ignorance depending on the causes. 

The urge to protect babies is inherent among mothers across the animal kingdom, including cats. Babies are fragile and helpless, so they need their mother’s warmth, care, and nutrition to survive. Amazingly, females across different species have natural maternal instincts that help them in raising their young. This also applies to felines, except in rare cases where they turn to filial cannibalism or the act of eating their own offspring.  

Cats eat kittens for different reasons, including birth defects or sickness, malnutrition, or human manipulation of the kittens. Let’s check out the details for these causes and understand why cats eat their kittens. 

Birth Issues

A cat may eat a sickly or dying kitten to protect the rest of the litter. Visual signs of a sick kitten may be easy for us or the cat to notice. However, cats may also use their sense of smell to detect disease and foresee the survival of their sick kittens. A cat’s sense of smell is 40 times better than ours. So, it’s not surprising if they’ll know their sick kitten’s fate through a sniff. 

Since a sick kitten may endanger its siblings, the mother cat will dispose of it by eating it. The mother cat wouldn’t want the rest of the litter to pick up the disease. If the weak kitten dies, it will also harbor bacteria that may harm the rest of the litter. 

Stillborn

The mother cat knows that a lifeless kitten is of no use and may even harm the litter. Since the kitten had no sign of life since birth, it may be decomposing soon. So, she assumes that this dead kitten may start smelling bad and attract bacteria. Exposure to bacteria may affect the remaining kittens. So, she’ll instinctually get rid of the stillborn kitten by devouring it.  

Threatened

Cats can get extra sensitive during pregnancy and after giving birth to their kittens. Like humans, they also go through hormonal changes in their bodies as well as physical pain during the entire process. So, any changes in the environment may easily stress them out. They are also very protective of their kittens. So, if they hear loud noises, see many people, or encounter other animals frequently, they may get threatened. 

When stressed or threatened, mother cats may start ignoring their kittens, or worse, eating them. This is common among young mother cats who aren’t mature enough to take responsibility for their new role. Thus, they manage stressful situations poorly and end up eating their kittens instead. 

Malnourished

Cats eating their kittens due to malnutrition rarely happens at home since domestic cats are well-fed. However, it may still happen in the wild or to stray cats who are deprived of enough food. Mother cats need to nurse their kittens to provide them with nourishment. This takes a toll on their bodies, thus, requiring more calorie intake to sustain enough nutrients in the body

However, not all cats have access to nutritious food. Plus, they also need to stay with their kittens to keep them warm, limiting them from hunting for food. So, because of malnutrition due to a lack of food, a cat eats kittens. It may sacrifice one or two to nourish its body and provide milk to the rest of the litter.

Cat doesn’t recognize her kitten

Too much handling of kittens by the owners may result in the mother cat eating its kittens. Why do mother cats eat their kittens in this scenario? Well, the kittens may lose their scent because of pet owners touching or holding them. Cats use their sense of smell to recognize the natural scent of their babies. If you touch or hold the newborn kitten, the scent will change and confuse the mother cat. 

Your cat may think that the kitten is not hers and could be a predator. So, to protect the other kittens, she’ll eat it. It’s best to avoid touching or holding the kittens for this reason. 

Do Male Cats Eat Kittens?

Male cats are less likely to eat kittens. However, they may attack newborn kittens due to dominance or to protect their territory. Male cats may kill kittens due to their unfamiliar scent. Cats recognize members of their family in the household through a common colony scent. Newborn kittens may not share the same smell yet. So, the male cat may assume the kittens are intruders or are members of another family. So, they attack them instead. 

Mating is another reason why male cats can be unfriendly towards kittens. Mother cats tend to be aggressive to other cats as it safeguards their offspring. So, it will not be receptive to a male cat’s call to mate. If the male cat wants to induce heat in the female for mating, he may attack the kittens. It’s uncommon for domestic cats to take advantage of a kitten’s vulnerability. But, in the wild, male cats may kill newborn kittens because they are easy prey, having no defense of their own.

Is It Normal For Cats To Eat Their Babies? 

It happens rarely, but yes, it is normal for cats to eat their young. It sounds terrifying, but cats aren’t the only animals that turn to filial cannibalism. Other species that eat their babies include polar bears, chimpanzees, dogs, and even fish. However, like cats, they also continue to take care of the remaining offspring. Researchers continue to study and try to understand this baffling act by these animals.

One study about fishes requiring paternal care has revealed that male fishes eat their babies to improve their future reproduction.  Another study done in 2016 mentioned that filial cannibalism may happen when the parent tries to lessen offspring overcrowding and improve nutrition. But it also says that the abundance of mates influences cannibalism as it’s easy to replace the lost offspring. This may or may not mirror a cat’s reasons for eating its kittens. But, it’s proof that it is indeed, normal for your pet to act that way. 

There are also other possible normal reactions a cat may show after giving birth. This includes ignoring or rejecting her kittens and aggression towards people or other animals. You may also notice your cat moving her kittens to another location. These situations may happen when there is a lot of human involvement or foot traffic in the area where the kittens are. The mother cat doesn’t feel secure so she tries to find another place to keep her babies. 

It’s best to stop yourself and other family members from touching the kittens and interfering with the mother cat. But, still continue to monitor your pet from a distance. Watch out for possible medical issues such as mastitis, hypocalcemia, endometritis, and milk fever.
