Why Does My Cat Chew Cardboard? [Causes & Remedy]

Cats are known for their quirky behaviors—whether it’s chasing after a laser pointer, climbing to the highest shelf, or curling up in the most unexpected places. But one behavior that often leaves cat owners scratching their heads is the tendency of some cats to chew on cardboard. It’s not just a fleeting interest, either. Many cats seem to enjoy gnawing on cardboard boxes, scratching posts, or even random pieces of packaging they come across. While this may seem odd, it’s a behavior that’s worth understanding. Is your cat simply being playful, or is there a deeper cause behind this strange habit? In this article, we’ll explore the various reasons why cats chew cardboard, when this behavior is normal, when it could be a cause for concern, and how you, as a cat owner, can respond.

Why Does My Cat Chew Cardboard?

Chewing cardboard can seem puzzling to cat owners, especially if their furry friends don’t seem to show any interest in chewing other types of objects. To get to the bottom of this behavior, it’s important to understand that cats are complex creatures with instinctual behaviors, emotional needs, and physical impulses that can all contribute to this action.

Cardboard, with its rough texture and pliability, provides a sensory experience that appeals to many cats. It satisfies an inherent need to chew, scratch, and manipulate objects with their mouths. But it’s not just about the physical satisfaction of chewing; it may also be connected to emotional or behavioral factors that we’ll delve into further in the next section.

Common Reasons Why Cats Chew Cardboard

1. Natural Instinct to Chew and Scrape
   Just as humans may crave a satisfying crunch, cats have natural instincts that drive them to chew and scratch. In the wild, cats use their teeth to tear into prey, chew bones, and shred materials for various purposes. Cardboard mimics some of these natural actions. When your cat chews on cardboard, it may be satisfying an innate urge to use their teeth in a way that feels instinctively comforting.

2. Boredom and Lack of Stimulation
   Cats are highly intelligent and curious animals. If they aren’t adequately stimulated, they may seek out ways to entertain themselves. Chewing cardboard is a behavior that may stem from boredom, particularly in indoor cats who may not have as much opportunity to hunt, explore, or engage with their environment. A cardboard box, in particular, provides an interactive surface that invites exploration, hiding, climbing, and chewing.

3. Teething or Dental Health Issues
   Kittens, just like human babies, go through a teething phase. During this time, they may chew on various objects to relieve discomfort. If your cat is under one year old, this could explain the chewing behavior. However, even older cats may chew cardboard if they have dental issues such as gingivitis or periodontal disease. The rough texture of cardboard could also help to scrape off plaque or soothe irritated gums.

4. Anxiety or Stress
   Stress and anxiety are significant contributors to many unusual cat behaviors, including chewing on cardboard. Cats are creatures of habit and routine, and disruptions in their environment, such as a change in the household or unfamiliar guests, can trigger stress. In such cases, chewing can become a form of self-soothing, helping the cat deal with the emotional strain.

5. Nutritional Deficiencies
   While rare, nutritional deficiencies can also contribute to unusual chewing behaviors. If your cat isn’t getting the necessary nutrients from their food, they may turn to non-food items, including cardboard, to satisfy cravings. This behavior could be related to a lack of fiber or other essential nutrients in their diet. It’s important to ensure your cat is getting a balanced diet that meets their nutritional needs.

6. Pica
   Pica is a condition where cats (and other animals) eat non-food items, including cardboard, fabric, plastic, or even dirt. While pica can be a normal exploratory behavior in young cats, persistent chewing or eating of non-food items, particularly in adult cats, may be a sign of a deeper issue. Pica may be linked to medical or psychological factors, such as stress, boredom, or even underlying health problems.

When To Be Concerned

While chewing on cardboard is common, it’s important to recognize when this behavior may be a cause for concern. If your cat’s cardboard-chewing becomes excessive or is paired with other unusual symptoms, it may indicate a health or behavioral issue. Here are a few red flags to watch for:

1. Excessive Chewing or Ingestion
   If your cat is chewing on cardboard constantly or eating large amounts, it could lead to digestive issues. Ingesting non-food objects may result in blockages, discomfort, or even vomiting. In extreme cases, this could require surgical intervention.

2. Behavioral Changes
   If the chewing is accompanied by changes in your cat’s behavior—such as increased aggression, withdrawal, or excessive vocalization—it could indicate stress, anxiety, or depression. Changes in behavior often require professional assessment to rule out underlying issues.

3. Weight Loss or Poor Coat Condition
   Unexplained weight loss, a dull coat, or signs of malnutrition could indicate a health problem such as a nutritional deficiency or an underlying medical condition that is contributing to the chewing behavior. If your cat seems to be losing weight or exhibiting signs of poor health, a vet visit is warranted.

4. Persistent Pica
   If your cat consistently chews on non-food items, such as cardboard, fabric, or plastic, it could be a sign of pica. Pica often warrants a deeper investigation into your cat’s mental or physical health, particularly if the behavior is occurring in an older cat that was not previously prone to such actions.

How To Respond As A Cat Owner

If your cat’s cardboard chewing is due to boredom or playfulness, there are several ways to redirect this behavior:

1. Provide Alternative Chewing Options
   Offering your cat appropriate alternatives, such as chew toys or dental chews, can help satisfy their need to gnaw without damaging household items. Cat-specific cardboard toys are also a good option, as they allow your cat to engage in the same chewing behavior without causing harm.

2. Increase Enrichment
   To prevent boredom-driven chewing, create an enriching environment for your cat. Interactive toys, puzzle feeders, climbing trees, and windowsills for bird-watching can help keep your cat mentally and physically stimulated. The more engaged your cat is, the less likely they will turn to cardboard for entertainment.

3. Regular Playtime
   Spending quality time with your cat through play helps burn off excess energy and provides a bonding experience. Engaging in interactive play, such as using feather wands or laser pointers, can keep your cat distracted from cardboard and promote physical activity.

4. Monitor Stress Levels
   If your cat is chewing cardboard due to stress or anxiety, identify and address the source of their discomfort. Creating a calm environment, providing safe spaces, or using calming products like pheromone diffusers can help ease anxiety.

5. Ensure Proper Nutrition
   Make sure your cat’s diet is well-balanced, rich in essential nutrients, and appropriate for their age and health status. If you suspect a deficiency, consult with your veterinarian to adjust their diet accordingly.

When To Consult A Veterinarian

If your cat’s cardboard chewing seems excessive, or if there are other concerning symptoms, it’s time to consult a veterinarian. A vet can perform a thorough examination to rule out medical conditions, including dental issues, gastrointestinal problems, or nutritional deficiencies. If your cat’s chewing is related to behavioral issues such as anxiety or pica, the vet can help you explore treatment options, which may include behavioral therapy or medication. Additionally, if your cat is regularly ingesting non-food items, the vet can advise on how to prevent health complications such as blockages or poisoning.

Conclusion

While chewing on cardboard may seem like an odd behavior, it is often a natural, harmless part of a cat’s instinctual toolkit. However, when it becomes excessive or is accompanied by other concerning signs, it’s important to take action. Understanding why your cat chews cardboard—from boredom to nutritional deficiencies—can help you address the behavior appropriately. By providing alternative activities, ensuring adequate stimulation, and maintaining a balanced diet, you can guide your cat toward healthier outlets for their chewing instincts. Always consult with a veterinarian if you have concerns about your cat’s behavior or health.
