Cats are curious creatures that love to explore their surroundings, including the fridge. While cats are obligate carnivores and require a diet rich in protein, they can also benefit from some human foods in moderation. This guide covers what is safe, what to avoid, and how to serve fridge foods appropriately.
The Basics of a Cat’s Diet
Cats are obligate carnivores, which means they require a diet rich in animal protein to thrive. Their digestive system is designed to process meat, and they have a limited ability to digest carbohydrates. A cat’s diet should be nutritionally balanced and provide all the necessary nutrients — protein, fat, vitamins, and minerals — in the right proportions.
Protein
Protein is essential for a cat’s growth, maintenance, and repair of body tissues. It is the most important nutrient in a cat’s diet, and cats require a higher protein intake than dogs or humans. High-quality animal protein from meat, fish, and poultry should form the foundation of every meal.
Fat
Fat is a concentrated source of energy and provides essential fatty acids important for maintaining healthy skin and coat, and for proper brain and eye development. Cats require a diet reasonably high in fat, balanced with other nutrients.
Carbohydrates
Cats do not require carbohydrates in their diet, but they can digest small amounts. Diets high in carbohydrates can lead to obesity and other health problems, so carbs should remain a minimal part of any cat’s intake.
Vitamins and Minerals
Cats require calcium, phosphorus, potassium, and magnesium, as well as vitamins A, D, E, K, the B vitamins, and taurine for proper growth and health.
Water
Water is essential for regulating body temperature, aiding digestion, and keeping the kidneys functioning properly. Cats should have access to fresh, clean water at all times. Wet food and fresh prey also contribute meaningful moisture to the diet.
What Can Cats Eat From the Fridge?
Here is a breakdown of what cats can and cannot safely eat from common fridge staples.
Safe Foods
- Cooked lean meat: Cats can safely eat cooked, lean meats such as chicken, turkey, beef, lamb, and pork. Make sure the meat is thoroughly cooked and remove any skin and bones before feeding.
- Cooked eggs: Cats can enjoy a small portion of scrambled or boiled eggs. Avoid raw eggs, which can harbor harmful bacteria.
- Plain cooked rice: Plain rice is easy to digest and can help settle an upset stomach.
- Cooked vegetables: Cats can handle small amounts of cooked carrots, green beans, and peas. Always avoid onions, garlic, and other alliums, which are toxic to cats.
Foods to Avoid
- Raw meat: Raw meat can contain harmful bacteria such as salmonella and E. coli. Always cook meat thoroughly.
- Chocolate: Contains theobromine, which is toxic to cats even in small amounts.
- Grapes and raisins: Can cause kidney failure and should be kept away from cats entirely.
- Onions and garlic: All alliums are toxic to cats and should never be fed in any form.
How to Serve Fridge Foods
- Serve at room temperature: Cold foods can upset a cat’s stomach. Let refrigerated foods come to room temperature before serving.
- Skip the microwave: Microwaving can create hot spots that burn a cat’s mouth. Warm food gently by placing the bowl in warm water instead.
- Serve small portions: Introduce new foods gradually and watch for any signs of digestive upset.
Treats and Occasional Foods
Treats should make up no more than 10% of a cat’s daily caloric intake. This number varies by weight, age, and activity level, so consult your vet for a personalized guideline.
What Treats Are Safe?
- Plain cooked meat: Small pieces of chicken, turkey, beef, or lamb with no seasoning or sauce are ideal.
- Green beans: Cooked and cut into small pieces make a low-calorie, crunchy treat.
- Banana: Cats can eat a small bite of banana occasionally, though the sugar content means it should be a rare treat.
- Broccoli: Safe in small cooked amounts and cut into small pieces.
- Plain unsweetened yogurt: A source of probiotics in small amounts — avoid any with added sweeteners or flavors.
Alternatives to Treats
- Puzzle toys: Fillable toys that dispense kibble or treats provide mental stimulation and make feeding more engaging.
- Catnip: A fun and safe way to give your cat an enjoyable experience without added calories.
- Playtime: Interactive play is one of the best ways to bond and reward your cat without affecting their diet.
Leftovers and Human Foods
Leftovers can add variety to a cat’s diet, but freshness matters. Avoid serving anything that has been sitting out or in the fridge for too long.
What Leftovers Are Safe?
- Skinless, boneless cooked chicken or turkey
- Cooked fish without bones
- Plain cooked grains like barley, corn, or couscous in small amounts
- Plain yogurt or mild cheese in very small amounts
How to Serve Leftovers
Make sure food is fresh and has not been out of the fridge for more than two hours. Warm it gently if needed, confirm there are no hot spots, and serve in small amounts. Monitor your cat’s reaction when introducing something new — if they show signs of digestive upset, discontinue that food.
Human Foods to Avoid
- Onions and garlic (all alliums)
- Grapes and raisins
- Chocolate
- Dairy products in large amounts
- Raw fish or raw meat
- Foods containing caffeine or alcohol
Health Concerns and Considerations
When offering fridge foods, keep the following in mind:
Illnesses and Infections
Undercooked or old meat can harbor pathogens like salmonella. Cook meat thoroughly and pay attention to food safety dates. Stay alert to any recalls or contamination alerts.
Digestive Issues
Introduce new foods slowly and in small portions. Dairy products may cause loose stools in some cats due to lactose intolerance. If a food consistently causes digestive problems, remove it from the rotation.
Pregnancy and Lactation
Pregnant and lactating cats have elevated protein and calorie needs. Consult your veterinarian to ensure their diet fully meets these increased requirements.
Special Diets
Cats managing diabetes, kidney disease, or other chronic conditions often require strict dietary management. Always check with your vet before adding new foods for a cat on a prescribed diet.
