What can’t cats eat? Knowing which human foods are safe and unsafe for your feline friend is crucial for their health and well-being. At solcat.net, we provide you with a detailed guide on dangerous food for cats, ensuring you can make informed decisions. Discover what foods to avoid to keep your cat healthy and happy.
1. Understanding Your Cat’s Dietary Needs
Cats are obligate carnivores, meaning their bodies are designed to get nutrients primarily from animal protein. According to research from the Cornell Feline Health Center, in July 2025, a diet rich in animal protein is crucial for their overall health. While some human foods are safe in moderation, others can be harmful or even toxic. Understanding these differences is key to ensuring your cat’s safety.
2. Foods Cats Should Absolutely Avoid
What can’t cats eat that poses significant health risks? Certain human foods are extremely dangerous and should never be given to cats. These foods can cause a range of issues from digestive upset to severe organ damage.
2.1. Fruits to Avoid
- Grapes and Raisins: Can cause kidney failure and gastrointestinal problems.
- Oranges: The seeds, leaves, stem, and peel contain oils that are poisonous to cats. Citrus fruits are also very acidic and can upset your cat’s stomach.
- Cherries: All parts of the cherry plant except the ripe fruit are toxic, including pits, stems, and leaves.
- Plums: The seeds, stems, and leaves contain cyanide, especially dangerous when wilted.
2.2. Vegetables to Avoid

3. Safe Human Foods for Cats in Moderation
What can’t cats eat doesn’t mean they can’t have any human food. While a cat’s primary diet should consist of high-quality cat food, some human foods are safe in small amounts. Remember, treats should only make up about 10% of your cat’s daily calorie intake.

- Blueberries: Rich in vitamin C and antioxidants, protecting cells from oxidative damage.

4. Human Foods to Give Cats with Caution
What can’t cats eat is often clearer than what they can eat with caution. Some foods are not inherently toxic but can cause problems if given in large quantities or to cats with certain health conditions.
4.1. Fruits to Give with Caution
- Avocado: The pit, skin, and leaves contain persin, which can cause poisoning in some animals. Give the flesh in very small amounts due to high-fat content.
- Peaches: Small amounts of peeled peach are generally safe, but too much can cause stomach upset and diarrhea due to high sugar content. Remove the pit to avoid cyanide exposure and choking hazard.
4.2. Vegetables to Give with Caution
- Potatoes: Raw potatoes contain solanine, a toxin. Cooked potatoes (boiled or baked) are safe in moderate amounts. Avoid fried potatoes due to high-fat content.
- Spinach: Avoid if your pet has kidney or digestive tract problems due to calcium oxalates, which can cause stone formation. Healthy cats can consume small quantities.
- Broccoli: Full of vitamins and minerals but can cause constipation. Give small amounts, boiled and unseasoned.
- Tomatoes: The leaves and skin contain solanine, which is toxic. Ripe and peeled tomatoes are safer.
- Corn: Not toxic but offers little nutritional value. Small amounts are fine, but large quantities can affect the digestive system. Serve boiled or cooked without spices, sauces, or oil.
4.3. Other Foods to Give with Caution
- Tuna Fish: Canned tuna prepared for cats is safe, but tuna for humans can be high in unsaturated fats. A tablespoon as a snack is okay, but constant consumption can be harmful.
- Bread: Small amounts are safe, but bread contains no nutritional value for cats.
- Peanut Butter: Safe in very small amounts (a teaspoon to a tablespoon). High in fats and carbs, which cats can’t digest well. Its sticky texture can also present a choking hazard.
5. Understanding Food Allergies in Cats
Like humans, cats can have food allergies or sensitivities. Common allergens include beef, fish, chicken, and dairy. Symptoms of food allergies can include:
- Itching and skin irritation
- Vomiting
- Diarrhea
- Hair loss
- Inflammation
If you suspect your cat has a food allergy, consult your veterinarian for diagnosis and management options.
6. Nutritional Needs of Kittens
What can’t cats eat also applies to kittens, but with additional considerations. Growing kittens need kitten food or food labeled for all feline life stages. Introduce new foods slowly and in small amounts to avoid digestive upset. Safe options include:
- Scrambled eggs
- Cooked meat and fish
- Salad greens
- Pumpkin
These foods should not make up more than 10% of your kitten’s daily calorie intake. Offer one new food at a time.
7. Safe Treats and Snacks for Cats
Besides human food, several commercial cat treats are available. Look for treats that are low in calories and made with high-quality ingredients. Always read the label to ensure the treat is appropriate for your cat’s age and health condition.
7.1. Examples of Safe Treats
- Freeze-dried meat treats
- Dental treats for oral health
- Soft treats for older cats with dental issues
8. Importance of Proper Hydration
Cats are prone to dehydration, especially if they primarily eat dry food. Ensure your cat has access to fresh, clean water at all times. You can also increase their water intake by:
- Offering wet food
- Using a water fountain to encourage drinking
- Adding unflavored broth to their food
9. Monitoring Your Cat’s Diet and Health
Regularly monitor your cat’s weight and body condition. Consult your veterinarian if you notice any sudden weight loss or gain, changes in appetite, or digestive issues. A balanced diet, regular exercise, and routine veterinary check-ups are key to maintaining your cat’s health.
10. Creating a Safe and Healthy Environment for Your Cat
Preventative measures are crucial to avoid accidental ingestion of harmful substances.
- Store all medications, cleaning products, and chemicals out of your cat’s reach.
- Keep toxic plants out of your home or in areas where your cat cannot access them.
- Educate family members and visitors about foods that are dangerous for cats.
11. What to Do If Your Cat Eats Something They Shouldn’t
If you suspect your cat has ingested something toxic, contact your veterinarian or an animal poison control center immediately. Provide as much information as possible, including:
- What your cat ate
- How much they ate
- When they ate it
- Your cat’s symptoms
Do not induce vomiting unless directed by a veterinarian.
Pro Tip: Pet insurance can help you cover the cost of vet bills if your cat eats something they shouldn’t.
12. Addressing Common Cat Behavior Problems
Understanding your cat’s behavior can help you create a more harmonious environment. Some common behavior problems include:
- Scratching furniture: Provide scratching posts and redirect your cat’s scratching behavior.
- Inappropriate elimination: Rule out medical issues and ensure the litter box is clean and accessible.
- Aggression: Identify the cause of aggression and consult a behaviorist for guidance.
13. The Benefits of Pet Insurance for Cats
Pet insurance can provide financial protection in case of unexpected veterinary expenses due to accidents, illnesses, or injuries. Consider enrolling your cat in a pet insurance plan to ensure they receive the best possible care without breaking the bank.

- Accidents and injuries
- Illnesses
- Chronic conditions
