Human Foods Which Cats Can't Eat

Human Foods Which Cats Can't Eat | Feline Nutrition
Alcohol*

Alcohol can cause intoxication, gastrointestinal irritation, respiratory distress, coma, and death.

Apricot, cherry, peach pits, apple seeds*

All of the above contain cyanogenic glycosides which will result in cyanide poisoning. This interferes with the ability of the blood to release oxygen into the tissues, so the cat effectively suffocates while his blood is full of oxygen. [1]

Avocado*

Avocado contains a toxin known as persin. It is found in all parts of the avocado and is toxic to most domestic animals.

The symptoms include gastrointestinal irritation, vomiting, diarrhea, respiratory distress, congestion, fluid accumulation around the tissues of the heart and even death. [1]


 

Caffeine* See chocolate, coffee, and tea.

Citrus

May cause vomiting in cats.

Cooked bones

Cooked bones can splinter and cause an obstruction in the gastrointestinal tract, therefore they should be avoided.

Chocolate, Coffee, and Tea*


 

Chocolate contains naturally occurring methylxanthines caffeine and theobromine. The concentration of theobromine is much higher than that of caffeine, but both cause toxicity in cats (and dogs). These chemicals act as a diuretic, causing the body to lose fluids, act as a cardiac stimulant, causing it to race and is also a central nervous system stimulant.

All types of chocolate should be avoided, including dark, milk, white and cocoa powders.


 

Grapes and raisins*

These have been known to cause kidney damage. The active ingredient hasn't been identified.

Macadamia nuts*

Macadamia nuts have been known to cause tremors and muscle weakness in dogs, therefore it's best to apply caution and avoid giving them to cats.

Milk

While this won't kill your cat, some cats are lactose intolerant and drinking cow's milk will cause a tummy upset.

Weaned cats no longer need to drink milk, however, if you do want to give your cat some milk as an occasional treat them the best solution is to buy some cat milk from your supermarket.


 

Mushrooms*


 

There are many types of mushrooms which are poisonous. While dogs are far more likely to eat mushrooms than cats, it is advised you avoid giving your cats any type of mushrooms to be on the safe side.


 

Fat

While fat isn't toxic to cats per se, it's not healthy to routinely feed your cat a diet high in animal fats as it will lead to obesity. Large amounts of fat can also cause pancreatitis.

Liver

Small amounts of liver are fine to eat, but if fed too often it can result in Vitamin A toxicosis.

Onion and Garlic*

Onions contain sulfoxides and disulfides which damage red blood cells and can cause haemolytic anaemia.

Be careful when feeding your cat human foods, some people will recommend baby food for a cat who's lost his appetite. This is fine, but make sure the food doesn't contain any onion, flakes, powder etc.

Onion causes greater problems than garlic.


 

Potato (green parts and eyes)*


 

These contain solanine glycosides which can cause vomiting, abdominal pain, bloody diarrhoea, nervous system stimulation, depression, trembling, paralysis and cardiac arrest.

Salt

Large quantities of salt can lead to an electrolyte imbalance.


 

Tomato*

See potatoes.

Tuna

This is another food which is fine to feed as an occasional treat, but mustn't be fed regularly, as it can lead to a condition known as Steatitis or Yellow Fat Disease.

Xylitol* Xylitol is a compound found in sugar-free gum. When consumed it causes a sudden release of insulin which can lead to hypoglycemia (low blood sugar) which is life threatening.
Yeast dough


 

This can expand in the stomach causing bloating and discomfort.

Other foods which your cat shouldn't eat:

  • Soy and rice bran

  • Raisins

  • Rhubarb

  • Spoiled or mouldy food. If it has gone off, don't give it to your cat.

  • Hops

It is always a good idea to check with your vet before giving your cat food which is meant for human consumption, just to be on the safe side.

What should I do if my cat has consumed one of the above foods?

Some of the foods on this list can be consumed in small amounts without ill effects, however, long term they can cause issues. Other types of food can cause acute, life-threatening disturbances and require immediate veterinary care. I have put an * next to these foods. If in any doubt, call your veterinarian or your poisons hotline.
