Cats licking plastic is a peculiar behaviour that has puzzled many pet owners. While it is not necessarily harmful, chewing on plastic can lead to serious health issues such as intestinal blockages and choking hazards. There is also a risk of strangulation or suffocation if a cat gets caught up in a plastic bag. One of the reasons cats are drawn to licking plastic is because of its texture—the smooth, cool surface probably feels good on their tongues. The crinkly sound of plastic bags may also appeal to their instincts to hunt, as it resembles the sound of prey in grass and leaves. Additionally, some plastics may carry food scents or residues, or contain ingredients like animal fats that smell appealing to cats. In some cases, licking plastic could indicate an underlying compulsive disorder called pica, which is linked to nutritional deficiencies, underlying health issues, or emotional states. If you notice your cat frequently licking plastic, it's important to supervise them and provide alternative stimulating toys to redirect their behaviour.

Plastic ingestion can cause intestinal blockages, leading to vomiting
Cats are drawn to plastic due to the inclusion of stearates, which are derivatives of animal fats used in the manufacturing process. The smooth, cool texture of plastic bags probably feels good on a cat's tongue. The crinkly sound of plastic bags might also intrigue cats and remind them of the sound of small rodents or birds, triggering their hunting instinct. Some plastic bags also contain biodegradable ingredients, such as animal fat, fish oil, or cornstarch, which can smell like a tasty treat to cats.
However, while licking plastic is not necessarily unsafe, chewing and ingesting plastic can lead to serious health issues, such as intestinal blockages. Plastic ingestion can cause intestinal blockages, especially if the pieces are mixed with other materials, like string or bedding. This can lead to vomiting, constipation, lethargy, and loss of appetite. Therefore, it is important to supervise cats around plastic items and provide them with alternative stimulating toys and sensory enrichment. If a cat starts chewing on plastic, it may be time to visit the vet to address any potential underlying nutritional deficiencies or psychological stress that could be causing this behaviour.

Pica, a compulsive eating disorder, may cause cats to lick plastic
Pica is a compulsive eating disorder that causes cats to lick and eat non-food items, including plastic. While the science behind this disorder is not yet fully understood, it is believed that the behaviour becomes obsessive due to increased reward sensations. Cats with pica may be attracted to plastic because of its texture, sound, taste, and motion.
Pica in cats can be caused by various factors, including nutritional deficiencies, underlying health issues, and emotional states. Nutritional deficiencies, such as a lack of high-quality animal proteins, essential amino acids, fatty acids, vitamins, and minerals, can contribute to the development of pica. Underlying health issues, such as endocrine diseases like diabetes mellitus, hyperthyroidism, anemia, and liver disease, can also play a role. Additionally, the emotional state of the cat, including stress, boredom, anxiety, and compulsion, can trigger pica.
Certain cat breeds, such as Siamese, Birman, and Oriental, have a higher predisposition to develop pica. Age is also a factor, with younger cats and kittens being more likely to engage in pica behaviours out of curiosity, teething, or attraction to animal-based stearates in plastic.
If you suspect your cat may have pica, it is important to consult a veterinarian. They may recommend blood tests, urinalysis, or other diagnostic examinations to identify any underlying causes. Treatment options can include dietary changes, supplements, behaviour modification plans, and medication to address compulsive or anxiety-related behaviours.
While licking plastic may not be inherently unsafe, chewing and ingesting plastic can lead to serious health risks for cats, including intestinal blockage, tearing of the digestive tract, and toxicity. Therefore, it is crucial to supervise your cat's interaction with plastic and provide safe alternatives, such as indoor cat grass and toys filled with catnip.

Cats may be attracted to the texture, taste, and smell of plastic
The taste of plastic can also be appealing to cats. Some plastics contain biodegradable ingredients, such as animal fat, fish oil, or cornstarch, which can be enticing to cats. Additionally, plastic bags can carry the scent or residue of food, which may attract cats. The strong sense of smell of cats, with 200 million scent receptors in their noses, can detect appealing odours on plastic that humans cannot.
While licking plastic is not necessarily harmful, ingesting plastic can lead to health issues. Plastic can harbour bacteria, especially if it has been exposed to food or the environment. Ingesting these bacteria can lead to infections or gastrointestinal problems. Additionally, chewing on plastic can create sharp edges that can injure the mouth or throat and small pieces of plastic can break off and cause choking. If cats swallow plastic, it may cause intestinal blockages. Therefore, it is important to supervise cats around plastic and provide alternative stimulating toys to redirect their attention.

Plastic bags may sound like prey, triggering a cat's hunting instinct
Cats are attracted to plastic bags due to their unique sensory properties. One of the most prominent theories suggests that the crinkly sound of a plastic bag mimics the noise made by small prey animals, such as rodents or birds, moving through grass or leaves. This sound triggers a cat's hunting instinct, making the bag an irresistible target for their natural curiosity and predatory behaviour.
The auditory appeal of plastic bags is not the only factor that makes them enticing to cats. Plastic bags also have a distinct texture that cats find appealing. The smooth and cool surface of plastic bags provides a novel tactile sensation for cats, especially when they lick it. This texture may feel good on their tongues, encouraging them to continue licking and exploring.
In addition to the sound and texture, the smell of plastic bags can also be alluring to cats. Some plastics contain biodegradable ingredients, such as animal fats, fish oil, or cornstarch, which can emit enticing odours that cats interpret as potential food sources. Even plastic bags that don't contain these ingredients can have their own unique scent, which cats, with their incredibly sensitive sense of smell, can detect and find intriguing.
While licking plastic bags can be a harmless activity for cats, it's important for owners to monitor their interaction with plastic. If cats progress from licking to chewing or ingesting plastic, it can pose serious health risks, including intestinal blockages, choking hazards, and potential bacterial contamination. Additionally, some cats may develop a compulsive behaviour known as "wool sucking," where they become obsessed with licking or sucking on plastic or other non-food items, which can indicate underlying nutritional deficiencies or psychological stress.
To prevent potential health issues and compulsive behaviours, cat owners should supervise their pets' interactions with plastic bags and provide alternative forms of stimulation. Interactive toys, such as those designed like fishing poles, can simulate prey movements and provide mental and physical stimulation for curious and understimulated cats. Catnip toys, puzzle feeders, cat trees, and access to nature through a window can also offer safe and engaging distractions for cats, reducing their focus on plastic bags.

Cats may lick plastic due to boredom or a lack of stimulation
The smooth, cool surface of plastic bags may feel good on a cat's tongue, and the crinkling noise it makes may sound like prey to their instinctual hunt for rodents. Plastic bags can also retain food smells or juices from meat, fish, or other appealing items previously stored inside, making them more attractive to cats.
If your cat is licking plastic due to boredom or a lack of stimulation, it is recommended to provide them with plenty of mental and physical stimulation. This can include interactive toys, scratching posts, cat trees, and perches. Providing a variety of toys with different textures and rotating them regularly can help prevent boredom.
Additionally, ensuring your cat has access to a well-balanced diet that meets their nutritional needs is important. Nutritional deficiencies can lead to pica, a compulsive disorder where cats lick or eat non-food items like plastic. Consulting with a veterinarian before providing any supplements is advised.
While licking plastic may not be unsafe, chewing and ingesting plastic can lead to serious health issues, including intestinal blockages and choking hazards. It is crucial to keep plastic items out of your cat's reach and provide safe alternatives for their licking and chewing needs, such as indoor cat grass and toys filled with catnip.
