Suckling is a normal behavior that’s common to all young mammals. In cats, suckling coupled with kneading is their bodies’ feeding reflex. Also, they remain to do that until they’re at least four weeks old and they’re ready to eat solid food.

Yet, in some cases, some pets have longer weaning periods and others get weaned too early. Hence, that’s a few of the reasons cats suck on blankets and become more anxious even though they’re adults.  

Moreover, another factor that relates to why your cat sucks on blankets is the environment. According to research, cats feel anxious when they’re surrounded by noise or unfamiliar people. Thus, they succumb to the suckling behavior because it increases their oxytocin production.

Stress and Anxiety

The first and most noticeable reason why your cat sucks on blankets is stress and anxiety. To be precise, stress is the main factor that triggers all other diseases to kick in. Also, when coupled with anxiety, a cat’s immune system lowers and your pet becomes prone to UTI, aggression, and gastrointestinal issues.

On the other hand, keep in mind that your cat’s surroundings have a big impact on his health. Well, a noisy environment will make all pets uneasy. Thus, cats opt to find ways to ease themselves by suckling on toys or fabric, particularly wool.  


When cats don’t have enough active stimulation, they may get bored and act sleepy the whole day. However, in other cases, cats tend to find alternatives for stimulation, like suckling. As weird as it may look, a cat’s suckling behavior is usually not a hazardous situation. Yet, you have to keep in mind that it could also be due to internal factors like boredom. 

Well, blankets aren’t poisonous provided there’s a proper precaution. But, if cats ingest its tiny fibers, then that could be a problem. It could lead to stomach upsets or obstruction that may require surgery. In general, it’s a must for pet owners to provide engaging activities and toys for their cats to avoid boredom. 

Natural Instinct

All mammals are born with the urge to suckle. Well, come to think of it, kittens already how to suckle for milk and they didn’t even learn that since it’s their reflex. With that said, it’s normal for young cats to have a strong urge to suck

On the other hand, that instinct can get stuck into adulthood, and hence, that’s one factor why your cat still sucks on blankets. Plus, some cat breeds like orientals tend to continue their suckling habits later in life since they have longer weaning periods. 

Early weaning

Like babies, kittens need milk for nutrition. Moreover, they’re not supposed to be weaned unless they turn four weeks old. Yet, there are instances where breeders sell early-weaned kittens. According to vets, early weaning poses more risks for aggression, anxiety, and fearful behavior. 

In addition, when your cat sucks on blankets, then that’s what vets call non-nutritive suckling or simply coss-sucking. Cats depend on their mother’s milk, so when they no longer have that opportunity, they turn to suck on their littermates’ bodies to satisfy their reflexes. 

Gastrointestinal Issues

Although it looks harmless, play biting, licking, or even suckling on objects and fabrics pertains to gastrointestinal issues. Further, that behavior could be a sign of obstruction, food allergies, inflammatory bowel disease, or other problems that need medical attention. 

Plus, excessive suckling on objects doesn’t only lead to stomach upsets but also damage to household decor and blankets. On the other hand, the fact that your cat sucks on blankets can also lead to a destructive eating disorder called pica


Genetics plays a strong role in shaping a cat’s personality. To be precise, some are dominant and they like to engage in active games. While others are calm that they would prefer lying in bed all day. With that said, the situation where cats suck on blankets is also another genetic-driven factor. 

According to studies, breed and behavior are proportional. Plus, based on the findings, certain breeds like Burmese cats groom excessively while Turkish Vans tend to perform prolonged wool-sucking attributes. 

Are Cats Sucking On Blankets Bad? 

Wool sucking is not a cause for concern if it’s not that destructive. Vets stated that sucking is a normal behavior and sometimes, even adults still do that. It provides them with relaxation and comfort, and at the same time, eases their stress levels. 

Well, a good rule of thumb suggests that cats sucking on blankets is not a bad behavior provided that they don’t ingest fabric fibers. Plus, if that behavior is not excessive and it’s only very occasionally, then it doesn’t pose a threat. 

On the other hand, if it gets too much that the suckling leaves holes in the fabric, then your cat may also need redirecting activities. Suckling only happens when cats don’t feel satisfied, so they cure that dissatisfaction using their ways. 

As a pet owner, you can redirect that suckling behavior by getting your cat chew toys. Also, you may want to try engaging activities like playing with puzzles, incorporating treat dispensers, or getting them mechanical toys.

As a pet owner, you shouldn’t be concerned about your cat’s sucking behavior. Well, it’s okay to leave it alone just as long as it’s done moderately. Scientists explained that suckling is a normal mammal reflex and despite it looking unusual, it may be present in all ages.  

With that said, it’s also normal for cats to develop emotional attachments to their toys or bedding. Plus, if they feel the need to self-soothe, it’s common for cats to suck on their blankets. Yet, too much of anything is not good, so vets still recommend constant monitoring

On the other hand, if you’re bothered about why your pet behaves like that, then you can implement some ways to engage his interests. Without further ado, here are some tips on how you can stop your cat from sucking blankets. 

  • Gradually remove the blanket and replace it with a durable chew toy or treat-dispensing cat toy.
