As pet-parents, we’ll do just about anything to keep our furry companions healthy and happy, and it all starts with what goes into their food bowl! In this guide, we’ll unpack common behavioural feeding mistakes that can impact your cat’s health and habits, what cats can eat, and then we’ll break down a list of foods that should always stay off the menu, no matter how curious your cat might be.
The 5 most common cat feeding mistakes (and how to fix them)
We all want what’s best for our feline friends but sometimes, love in the form of extra treats or topped-up bowls can actually do more harm than good! Even the most caring cat parents can accidentally fall into feeding habits that lead to long-term health issues. Here are some common mistakes to avoid:
Mistake #1: Overfeeding and unrestricted ‘free-feeding’
Many cats will keep eating simply because the food’s there, and not because they’re actually hungry. Since they rarely have an ‘off’ switch, this can lead to one of the most common issues vets see: feline obesity.
Mistake #2: Not providing enough fresh water
Think your cat’s getting enough hydration from wet food alone? Not quite. Dehydration can sneak up quickly, especially in fussy drinkers.
Mistake #3: Feeding the wrong food (Sorry, dog food doesn’t count!)
While your cat might happily sneak a few bites from the dog’s bowl, their nutritional needs are completely different. Feeding meat or fish alone, or giving unnecessary supplements, can also throw things way off balance, especially for growing kittens. Cat nutrition should always be front of mind!
Mistake #4: Ignoring your cat’s life stage
Your kitten isn’t just a tiny adult cat, and your senior cat doesn’t have the same needs as a bouncy adolescent. Life stage matters more than you might think.
Mistake #5: Diet too high in treats
We know how easy it is to give in to those pleading eyes, the little paw taps, the hopeful meows. Treats are a lovely way to bond, but too many can quietly add up and throw off your cat’s balanced diet.
Foods you must never feed your cat: A comprehensive list
Even the most harmless-looking snack or houseplant can spell big trouble for your curious cat. While it’s tempting to share a treat or keep fresh flowers around the house, many everyday items can be toxic – or even fatal to our furry friends. To help keep your cat safe, here’s a clear breakdown of the foods, plants, and common household hazards to avoid.
Toxic human foods
What can’t cats eat? Some of our favourite pantry staples are dangerously toxic to cats. Even small amounts can cause serious illness. Here’s a list to keep in mind at all times:
- Onions and garlic: Found in many cooked meals, these can damage red blood cells and lead to anaemia.
- Chocolate: Contains theobromine and caffeine, both toxic to cats. Dark chocolate can be especially dangerous.
- Grapes: Even tiny amounts can cause acute kidney failure in cats. This includes raisins, sultanas and currants.
- Alcohol: No amount is safe. Alcohol can depress the nervous system and lead to liver damage or death.
- Xylitol: This artificial sweetener can trigger insulin release, leading to hypoglycaemia and even liver failure. Found in sugar-free gum or even some baked goods.
- Caffeine: Can cause restlessness, tremors, and heart palpitations in our furry friends.
- Raw meat, eggs and bones: While some pet owners opt for raw diets, feeding raw meat or eggs without veterinary guidance risks exposure to bacteria like salmonella. Cooked bones can splinter and cause choking or internal damage.
- Dairy products: Many cats are lactose intolerant, so milk and cheese can lead to upset stomachs, diarrhoea, or bloating.
Fatty trimmings, avocado, bread dough, fruit pits, seeds, corncobs, mushrooms and tomatoes are also considered unsafe for cats and should be kept off the menu.
Dangerous houseplants
Your indoor jungle might look beautiful, but some houseplants are extremely toxic to cats, even in small amounts. Toxic plants for cats include the following:
- Lilies (all varieties): Extremely toxic and potentially fatal. Even licking a few grains of pollen can cause sudden kidney failure.
- Oleander: Can cause both heart and kidney issues.
- Sago Palm: Ingestion can cause vomiting, liver failure, and death.
- Tulips & Daffodils: Can irritate the mouth and stomach, leading to vomiting and drooling.
If in doubt, research every new plant before bringing it into your home or stick to cat-safe options.
Common chemicals and medications
Cats can be highly sensitive to many everyday products. Even small doses of certain substances (harmless to humans), can cause severe reactions in our feline friends. Always store medications, cleaners, and essential oils well out of reach, and avoid using strong chemicals in areas your cat frequents. Keep an eye out on the following:
- Human medications (like Paracetamol or Ibuprofen): Just one tablet can be fatal. Never give human meds to cats unless directed by a vet. Ingesting these medications can cause kidney damage, liver failure, gastrointestinal ulcers, and other serious complications in cats.
- Household cleaners: Products with bleach, phenols or ammonia can cause chemical burns or poisoning.
- Essential oils and diffusers: Tea tree, eucalyptus, and citrus oils are particularly risky and should be avoided in any form.
Pro tip: If your cat eats something suspicious, don’t wait – contact your vet or a pet poison hotline immediately. When it comes to toxic foods and substances, speed can save lives.
The Great Debate: Is wet or dry food better for cats?
It’s one of the most common questions cat owners ask, and for good reason! Choosing between wet and dry food can feel like a big decision, especially when you’re trying to do what’s best for your cat’s health.
Wet food is a winner when it comes to hydration. With its high moisture content, it helps support urinary tract health and can be especially beneficial for cats who aren’t big drinkers. It also tends to be more palatable, which can be helpful for fussy eaters or senior cats with reduced appetites.
Dry food, on the other hand, is convenient to store and serve, especially for busy households. Some specially formulated dry foods can also help reduce plaque build-up and support dental health. It’s often more cost-effective and well-suited to measured free-feeding, if your cat can self-regulate!
Every cat is different, so consider your pet’s age, health, lifestyle, and preferences when deciding which food to offer.
When to call your vet: Signs of poisoning
If you suspect your cat has ingested something toxic, watch closely for these warning signs:
- Vomiting or diarrhoea
- Lethargy, weakness, or collapse
- Difficulty breathing or seizures
- Excessive drooling or pawing at the mouth
- Lack of appetite or unusual hiding
If you notice any of these symptoms, call your vet or an emergency animal hospital in your state or territory immediately. Quick action can be lifesaving, so don’t hesitate – even if you’re unsure. It’s always better to be safe when it comes to your cat’s health.
Frequently Asked Questions ( FAQsFrequently Asked Questions )
Got questions? We’ve rounded up some of the most common concerns cat owners have about feeding, treats, and keeping their furry friends safe, so you don’t have to guess!
Is it safe to give my cat a small amount of milk or cheese?
As tempting as it is to share, most cats are lactose intolerant, so milk and cheese can upset their tummy and cause unwanted messes. Stick to specially formulated cat treats instead!
Why is dog food bad for cats?
Cats have very different nutritional needs than dogs. Dog food lacks key nutrients like taurine, which cats need to stay healthy and happy. So, no swapping bowls!
How do I know if the cat food I'm buying is high quality?
Look for named animal proteins (like chicken or fish) at the top of the ingredients list, avoid fillers, and check if it complies with the Australian Standard (AS 5812). If it sounds like a mystery stew, your cat might think so too!
What should I do first if I see my cat eat something on the toxic list?
Don’t panic! Call your vet or emergency animal hospital right away. They’re the pros at handling this kind of situation fast and safely.
Food for thought
Feeding your cat well is one of the best ways to show you care, because a happy tummy means a happy kitty. While every cat is unique, knowing what to avoid and how to feed them right can help keep your feline friend healthy and thriving for years to come.
