If you have ever caught your cat chewing on plastic bags, licking walls, or gnawing on fabric, you have witnessed pica. It is not just a quirky habit, it is often a sign that something is off in your cat’s diet or health. Many owners feel frustrated and worried, but the good news is that switching to a high quality cat food can make a real difference. By addressing nutritional gaps, improving digestion, and supporting overall wellbeing, the right food can help reduce or even stop pica behaviors. Let us walk through exactly what to look for and why it works.
Why Diet Matters for Pica
Cats are obligate carnivores, meaning their bodies are designed to get nutrients almost exclusively from animal tissue. When a cat food is low in quality protein, missing key amino acids like taurine, or packed with cheap fillers, a cat’s body may send confusing hunger signals. This can lead to chewing on non-food items in an attempt to find missing nutrients. High quality cat food delivers complete, bioavailable nutrition that satisfies your cat’s biological needs. Look for foods where a named animal protein (like chicken, turkey, or salmon) is the first ingredient, and where the food is free from artificial colors, flavors, and unnecessary grains. A diet rich in animal-based protein and moisture (from wet food or raw options) is often the first step in stopping pica.
Some cats with pica are actually seeking fiber. A small amount of pure canned pumpkin or a high-fiber cat food can help satisfy that urge without letting them chew on dangerous objects.
Key Nutrients That Curb Pica
Certain nutrients are especially important for preventing pica. Taurine is essential for heart and eye health, and a deficiency can trigger odd behaviors. Omega-3 fatty acids (from fish oil or flaxseed) support brain health and reduce inflammation, which may calm obsessive tendencies. B vitamins, particularly B12 and niacin, help with energy metabolism and nerve function. Digestible fiber from sources like pumpkin or psyllium helps keep the gut moving and can prevent your cat from eating non-food items to aid digestion. When choosing a high quality cat food, check the guaranteed analysis for these nutrients, and consider rotating between a few high quality brands to ensure a broad nutrient profile.
Wet Food vs. Dry Food for Pica
Moisture matters. Many cats with pica are chronically dehydrated, which can lead to constipation or urinary discomfort. Wet food provides 70 to 80 percent moisture, helping your cat feel full and hydrated. Dry food, even high quality kibble, is often only 10 percent moisture. If your cat eats dry food, consider adding water or bone broth to it, or switching to a high quality canned food. Some cats also do well with freeze-dried raw food, which you can rehydrate. The key is to increase moisture intake, which supports kidney function and can reduce the urge to chew on non-food items. For cats who eat wet food, using an elevated bowl can make mealtime more comfortable and reduce neck strain. Check out our guide to Need Elevated Cat Bowls?

How to Transition Your Cat to a Pica-Preventing Diet
Switching foods abruptly can upset a cat’s stomach and make pica worse. Instead, over 7 to 10 days, mix increasing amounts of the new food with the old. Start with 25 percent new food and 75 percent old, then gradually shift. Watch for signs of digestive upset like vomiting or diarrhea. If pica behaviors increase during the transition, slow down. Some cats also benefit from a probiotic supplement to support gut health during the change. A healthy gut microbiome can reduce inflammation and improve nutrient absorption, both of which help curb pica. For recommendations, see our Cat Probiotic Supplement Guide: Top 5 Picks for 2026.
“A cat’s diet is not just about filling a bowl, it is about meeting deep biological needs. When those needs are met, the urge to chew on plastic and fabric often fades away.”
Additional Steps to Support Your Cat
Diet is powerful, but it works best alongside other changes. Make sure your cat has plenty of safe, appropriate chew toys (like silicone or rubber toys designed for cats). Provide environmental enrichment: climbing trees, window perches, and interactive play sessions. Stress is a major trigger for pica, so a calm home environment matters. If your cat seems anxious, a calming collar or pheromone diffuser can help. For more on that, check our 5 Best Cat Calming Collars (2026): Top Picks Compared. Also, keep dangerous items like plastic bags, cords, and fabric out of reach. Finally, always consult your veterinarian if pica persists, as it can sometimes signal an underlying medical issue like anemia, dental pain, or gastrointestinal disease. Your vet can run blood work to rule out these causes and help you tailor the diet further.
What to Look for on a Cat Food Label
When shopping for high quality cat food to prevent pica, read the ingredient list carefully. Look for: a named animal protein as the first ingredient (chicken, turkey, salmon, etc.), a statement from the Association of American Feed Control Officials (AAFCO) that the food is complete and balanced for your cat’s life stage, and no artificial preservatives like BHA or BHT. Avoid foods with vague terms like “meat meal” or “poultry by-product” unless the source is named. Wet foods with a high moisture content (over 75 percent) are ideal. If your cat eats dry food, choose one with at least 40 percent protein and less than 10 percent carbohydrates. Some premium brands even offer limited ingredient diets, which can help if your cat has food sensitivities that trigger pica. Remember, you do not need the most expensive brand, just the one that meets these quality standards.
Pica can be a symptom of a serious health issue. If your cat is eating non-food items frequently, especially if they are losing weight, vomiting, or having changes in appetite, please see your veterinarian before making dietary changes alone.
