What Can Cats Eat?

As a cat owner, you've probably noticed your feline friend showing interest in everything you eat—from roasted chicken to your morning toast. Whilst it's tempting to share your meals with those pleading eyes, understanding what cats can safely consume is crucial for their long-term health and wellbeing. Cats have unique nutritional requirements quite different from other pets, and some foods that are perfectly safe for humans can be downright dangerous for our whiskered companions. This guide will help you navigate the world of feline nutrition, ensuring your cat enjoys a healthy, balanced diet.

The Foundation: Commercial Cat Food

The easiest way to ensure your cat receives balanced nutrition is through high-quality commercial cat food. Look for products that list meat as the primary ingredient and meet AAFCO (Association of American Feed Control Officials) standards, which are recognised across Europe as well.

Wet food: Contains approximately 70-80% moisture, helping with hydration and particularly beneficial for cats prone to kidney issues
Dry food: More convenient and cost-effective, though typically higher in carbohydrates
Raw diets: Increasingly popular but require careful handling and veterinary guidance to ensure nutritional completeness

Most veterinarians recommend feeding adult cats twice daily, adjusting portion sizes based on your cat's weight and activity level.

Safe Human Foods for Cats

Several human foods can be offered to cats as occasional treats, provided they're given in moderation:

Cooked meats: Chicken, turkey, beef, and lamb (without seasoning or bones)
Cooked fish: Salmon, tuna, and sardines—excellent sources of omega-3 fatty acids
Eggs: Cooked only, as they provide high-quality protein
Cooked vegetables: Carrots, pumpkin, and sweet potato (cats are obligate carnivores, so vegetables shouldn't form a large part of their diet)
Plain cooked rice or pasta: In small amounts, occasionally helpful for digestion

Always ensure any human food is unseasoned, unsalted, and prepared without garlic or onions, which are toxic to cats.

Foods to Avoid Completely

Several foods pose serious health risks to cats and should never be offered:

Onions and garlic: Damage red blood cells and can cause anaemia
Chocolate: Contains theobromine, which can cause heart problems and neurological issues
Avocado: Contains persin, a compound toxic to cats
Grapes and raisins: Can cause kidney failure
Xylitol: An artificial sweetener that causes severe hypoglycaemia
Raw dough: Expands in the stomach and can cause bloating
Alcohol and caffeine: Both are toxic to cats
Raw fish: Can destroy thiamine (vitamin B1), leading to neurological problems

Special Considerations for Kittens and Senior Cats

Different life stages require different nutritional approaches. Kittens need kitten-specific food with higher protein and calorie content to support growth. Senior cats (aged 11+) benefit from joint-supporting supplements and may require lower-calorie foods if they become less active.

Hydration and Water Intake

Cats often don't drink enough water, particularly if fed primarily on dry food. Ensure fresh water is always available, and consider investing in a cat water fountain, as many cats prefer running water. Adequate hydration is essential for kidney health and overall wellbeing.
