What can t cats eat

Our cats are not only pets; they’re also our companions and confidants. And as their caretakers, it’s only natural for us to want to spoil them. But some foods and treats can pose serious risks to their health. Here we answer seven common questions about foods you should avoid feeding your cat.

1. Can Cats Have Milk, Cheese and Other Dairy Products?

Many of us grew up with the image of kittens drinking milk or cream in cartoons or picture books. But in reality, cats and dairy products don’t mix. Most cats are naturally lactose intolerant, meaning that cow milk and dairy products made from it — like cheese or cream — can upset their stomachs, causing vomiting and diarrhea.

And what about kittens? The same rule applies: Cow milk and byproducts should be avoided. For kittens that are too young to eat solid foods and don’t have a source of their mother’s milk, veterinarians recommend feeding kitten-specific milk formulas, which provide essential nutrients for growing kittens and are gentle on their tummies.

2. Can Cats Eat Chocolate?

Though most people find chocolate delicious, this cacao-based treat contains two ingredients that are toxic to cats: theobromine and caffeine. Both milk chocolate and dark chocolate can cause several dangerous symptoms, including:

  • Vomiting
  • Diarrhea
  • Increased body temperature
  • Rapid breathing or heart rate
  • Seizures

In cases of high exposure to theobromine and caffeine, cats can also suffer from heart failure, weakness or a coma.

3. Should Cats Eat Raw Eggs, Meat or Fish? 

If your cat loves hunting, you might assume it’s safe to feed them raw eggs, meat or fish. After all, what could be more natural than raw? However, these raw foods may contain dangerous E. coli and salmonella bacteria, which can cause diarrhea, vomiting and lethargy in cats. Exposing your cat to these pathogens can even prove fatal.

Raw egg whites also contain a protein called avidin. If consumed, avidin can prevent your cat from properly absorbing the B vitamin biotin, potentially causing skin conditions and a dull coat.

4. Is It OK for Cats to Eat Dog Food? 

If you also have a dog, chances are your cat has sampled their food from time to time. But while an occasional nibble likely won’t harm your cat, a steady diet of dog food instead of cat food can cause malnutrition. Cats need vitamin A, taurine and arachidonic acid — all essential nutrients not provided in dog food.

If your cat only eats dog food, they’re at risk for developing several conditions:

  • A lack of vitamin A can cause skin issues, a dull coat, muscular degeneration or night blindness.
  • A taurine deficiency can cause vision degradation, heart disease, unhealthy coat or skin, and lethargy.
  • A lack of arachidonic acid can cause liver and kidney problems.

5. Can Cats Have Bread and Yeast? 

Cats can safely eat bread on occasion, but note that bread contains no nutritional value for them (it has virtually no fat or protein), so it should not replace their normal cat food diet.

Yeast and raw bread dough are not safe for cats; after it’s eaten, the dough can rise in a cat’s stomach and cause dangerous digestive issues.

6. Can I Feed My Cat Tuna? 

What cat doesn’t enjoy tuna? This fish can serve as an occasional treat for your cat, but you should avoid feeding them a tuna-heavy diet. Tuna lacks several nutrients cats need to stay healthy, and too much tuna can lead to mercury poisoning. And, as noted above, you should never give your cat raw tuna.

7. Can Cats Eat Onions and Garlic? 

Onions, garlic and other members of the allium family, like chives and leeks, can cause anemia in cats. Whether raw, cooked, powdered or dehydrated, garlic and onions can damage a cat’s red blood cells, and can also cause nausea, abdominal pain, vomiting and diarrhea.

Remember that most cats are curious creatures, and love to investigate food that’s been left out on countertops or in sinks. If your cat can easily jump on a table or counter, make sure to keep dangerous or toxic foods well out of reach — sealed behind a closed pantry door or kept in a high-up cabinet.

There are lots of tasty human foods that can make your cat very ill. Any food not specifically designed for cats can affect the digestive system, causing vomiting, diarrhoea, or loss of appetite.

Foods that cats can’t eat include:

  • Alcohol
  • Chocolate
  • Tea, coffee and energy drinks
  • Cheese and milk
  • Fat trimmings
  • Raw eggs, raw meat and raw fish
  • Grapes and raisins
  • Onions and garlic
  • Xylitol

If you suspect your cat has eaten human food poisonous to cats try to determine how much she may have eaten and contact your vet for advice. If it’s out of hours, find your nearest emergency vet here.

In some cases, small quantities may not cause a problem but larger quantities may require urgent treatment.

As little as a tablespoon of alcohol can lead to problems for your cat. It can cause severe liver and brain damage.

Chocolate contains theobromine. While this bitter-tasting stimulant is found in all forms, it’s most concentrated in dark and unsweetened chocolate. Ingestion can cause heart problems, muscle tremors, or seizures. Chocolate also contains caffeine.

These contain caffeine — it can cause your cat to become restless, suffer from rapid breathing, heart palpitations and muscle tremors.

Perhaps surprisingly, dairy products are high on the list of what can cats not eat. This is because some cats are lactose intolerant so if they eat dairy products it can cause vomiting and diarrhoea.

Can cause vomiting, diarrhoea or a painful condition called pancreatitis (from excessive fat) and there is also a risk of Salmonella or E. coli associated with these foods.

Dogs can suffer acute kidney failure from eating grapes or raisins — and although toxicity in cats is only anecdotal we would strongly advise that you keep these foods out of reach of your cat.

All members of the onion family can cause problems if eaten in sufficient quantity. A little bit of onion or garlic in some sauce is not likely to cause any problems. However, eating a clove of garlic or a green onion may cause digestive upset. Eating some type of onion on a regular basis could cause anemia.

This is a sweetener used in a lot of sugar-free foods, especially chewing gum. There are no records of cats becoming ill from this product, but in dogs it can cause a severe drop in blood sugar — which can cause seizures and convulsions or even death — followed by liver failure. It’s better to be safe and not let your cat eat foods that contain this ingredient.

The best prevention is simply to keep your food out of reach of your cat. If you choose to give your cat human food, follow these guidelines:

  • The food should only be considered a treat and only given on the odd occasion to prevent gastrointestinal upset and nutritional imbalances
  • If you wouldn’t eat it, don’t feed it to your cat.
  • If you wouldn’t eat the food raw, then your cat shouldn’t either

If your cat has eaten food that can cause them harm, treatment is generally supportive until the symptoms resolve. This may involve hospitalisation, intravenous fluids (a drip) and blood tests to monitor organ function.
