What Is Pica in Cats?

Pica involves ingestion of non-food items. Frequently reported items which cats may chew include wool, fabric, wood, plastic, paper and plants (Case, 2003, Horwitz & Mills 2009). Often the molar teeth are used to chew holes in such materials.

Pica shouldn’t be mistaken for kitten behaviour of suckling which might persist into adulthood. When adult moggies exhibit suckling behaviours, material isn’t consumed, simply sucked repetitively and often accompanied with front paw kneading.

Likewise, many young moggies will chew and tear at objects when exhibiting predatory behaviour during play, pieces are torn off but NOT consumed.

Ingestion of bizarre objects can result in life-threatening internal blockages requiring urgent veterinary medical attention.

Why Do Cats Have Pica? Hypothesized Causes of Pica Explained

Cats know that meowing will get you to look at them, and making crinkling sounds can accomplish the same goal.

Since there’s no test to diagnose pica, veterinary professionals depend on owner’s home observations and note-taking. Theories of pica include:


 Pica is generally seen in breeds like Siamese, Tonkinese, and Burmese who are predisposed to eating wool or wool sucking. Other domestic kitties with no known Oriental ancestry like DSH and Ragdolls may also endure pica.

Dietary Deficiencies

Cats with prolonged nutritional deficiencies lacking adequate fat, minerals and/or vitamins in their food may ingest non-edible material, whilst other cases could also be due to dietary imbalance from lack of roughage, although a clear dietary insufficiency has yet to be documented.

Medical Reasons

Licking or absorption of weird substances has been correlated to Endocrine and Gastrointestinal conditions such as Hyperthyroidism, Diabetes, Inflammatory Bowel Disease (IBD), Gastric Motility, and hookworm infestation.

Two studies uncovered a high prevalence of pica diagnosed in cats with immune-mediated Hemolytic Anemia, Pyruvate kinase deficiencies, and Feline Infectious Peritonitis (FIP), but with lower occurrences (Isabelle Demontigny-Bédard, 2015). Infrequently, eating inappropriate things may also happen with medical issues like fatty liver disease.

Additionally, neurological disorders and cancer (i.e., brain tumours) can disrupt appetite control and contribute to uncommon cravings resulting in pica.

Behavioural Hypothesis

Pica prevalence is considerably greater in felines housed exclusively indoor. Potential contributing factors include boredom, anxiety, frustration and lack of social contact.

High reinforcement history to things can have an accentuating component, increasing the likelihood of the behaviour repeated, inadvertently reinforced by the owner when the cat steals food items with plastic wrapping.

Obsessive-Compulsive Disorder

According to certain literature pica may be considered an obsessive-compulsive disorder in anxious moggies. Gnawing or sucking on objects releases endorphins and serves as comfort.

Distress can exacerbate pre-existing pica and chomping of things is also used as a coping mechanism.

Stressful life events like house move, new pet adoption and owner death can trigger compulsive ingestion of non-food items in individual cats.

    I have a 9 year male Himalayan. I adopted a 1 year old female that was hanging with ferals. Both are neutered. My boy couldn’t wait to meet her. I kept them separated for 4 weeks, they were immediate friends; that was 3 years ago. In the past 2 years during the middle of the night my 3 year old has let out blood curtling screams/sounds and attacks my loving mellow Hymalayan. I have to jump out of bed and grab my boy close the bedroom door and take him in bed with me where he stays until morning. When I open the bedroom door they smell each other and all is well. Why is this happening?

      Hi Pat,

      Thank you for your question.

      If this has been happening for 2 years continually same time, it’s likely your household is getting visited by either a feral/stray cat or a nocturnal animal causing redirected aggression.

      When a cat is agitated or frustrated by a stimulus, they respond by redirecting the attack towards the closest target, in this case her mellow brother instead of the source.

      Place a webcam or pet-camera with night vision before heading to bed to inspect both indoor/outdoor environments. If indeed you have a night visitor, close all blinds, change your shades or place a privacy window film.

      Hope this helps

    My husband uses oxygen tanks on a daily basis and our cat punctures the tubing by chewing on it. Can you suggest any spray or solution that I can apply to deter her actions. I’ve tried vinegar and various cooking extracts such as vanilla, almond, and peppermint to no avail. Any other suggestions would be greatly appreciated. Thank you,

      I think you’ll find that this article addresses your problem a bit better and gives some solutions. The sprays aren’t very effective, in my experience, so it may work better to focus on distraction, deterring, and giving her other things to chew on and play with. Wishing you all the best!
