Are these everyday foods secretly harmful? What pet owners need to know

For many of us, our pets are more than just animals⁠—they’re beloved family members. We share our homes, our routines, and sometimes even our snacks with them. 

But did you know that some of the most common foods in your kitchen could pose serious risks to your furry friends? 

Whether you’re a seasoned pet owner or have just welcomed a new companion into your life, it’s crucial to be aware of the hidden dangers lurking in your pantry and fridge. 

The Usual Suspects: Foods to Keep Away from Pets

While it’s tempting to slip your dog a bit of your dinner or let your cat lick your plate clean, not all human foods are safe for pets. 

In fact, some can be downright dangerous—even in small amounts. Here are some of the most common culprits:

1. Chocolate  

Most pet owners know chocolate is a no-go for dogs, but it’s also toxic to cats and birds. Chocolate contains theobromine and caffeine, both of which can cause vomiting, diarrhoea, rapid breathing, increased heart rate, and even seizures.

2. Grapes and Raisins  

These seemingly harmless fruits can cause sudden kidney failure in dogs and, to a lesser extent, cats. Even a small handful can be enough to trigger a reaction.

3. Onions and Garlic  

Whether raw, cooked, or powdered, onions and garlic can damage your pet’s red blood cells, leading to anaemia. Symptoms may not appear immediately, so it’s important to keep these ingredients well out of reach.

4. Xylitol (Artificial Sweetener)  

Found in sugar-free gum, lollies, and even some peanut butters, xylitol can cause a rapid insulin release in dogs, leading to hypoglycaemia (low blood sugar), seizures, liver failure, and even death.

5. Avocado  

While avocado is a superfood for humans, it contains persin, which can be toxic to birds, rabbits, and some other animals. Dogs and cats are less sensitive, but avoiding sharing your smashed avocado toast is still best.

6. Alcohol and Caffeine  

Even small amounts of alcohol or caffeinated drinks can be dangerous for pets, causing vomiting, diarrhoea, difficulty breathing, tremors, and more.

7. Cooked Bones  

It’s a common misconception that all bones are good for dogs. Cooked bones can splinter easily, causing choking, blockages, or tears in your pet’s digestive tract.

8. Dairy Products  

Many pets, especially adult cats and dogs, are lactose intolerant. Feeding them milk, cheese, or ice cream can lead to upset stomachs and diarrhoea.

Why Are Pets So Sensitive to Human Foods?

Animals metabolise food differently from humans. What’s harmless—or even healthy—for us can be toxic for them. 

For example, dogs lack the enzyme needed to break down theobromine in chocolate, and cats’ livers can’t process certain compounds found in onions and garlic. 

Even small amounts can build up in their systems and cause harm.

What to Do If Your Pet Eats Something Dangerous

If you suspect your pet has eaten something toxic, don’t wait for symptoms to appear. Call your vet or the Animal Poisons Helpline (1300 869 738 in Australia) immediately. 

Try to provide information about what was eaten, how much, and when. Quick action can make all the difference.

Safe Treat Alternatives

Want to spoil your pet without risking their health? Here are some safe options:

For dogs: Carrot sticks, apple slices (without seeds), plain cooked pumpkin, or small chicken pieces.
For cats: Cooked lean meats, a bit of plain tuna (in water, not oil), or commercial cat treats.
For birds and small animals: Consult your vet, as their dietary needs can be particular.

Tips for Keeping Your Kitchen Pet-Safe

• Store dangerous foods out of reach, ideally in cupboards or the fridge.
• Remind guests not to feed your pets from the table.
• Be mindful of food scraps and rubbish bins—curious pets can get into trouble quickly.
• Learn the signs of poisoning: vomiting, diarrhoea, lethargy, tremors, and changes in behaviour.

A Final Word: When in Doubt, Leave It Out

It’s always better to be safe than sorry. If you’re unsure whether a food is safe for your pet, err on the side of caution and don’t share it. Your furry (or feathered) friend will thank you for it in the long run.
