9 foods that are toxic to cats

This is not in order of toxicity


Chocolate contains theobromine. While this stimulant is found in all forms, it is most concentrated in dark and unsweetened chocolate. Ingestion can cause heart problems, muscle problems or seizures. Chocolate also contains traces of caffeine.

Cheese and Milk

Cheese and milk are both dairy products, these are high up on the list of things cats can not eat. It is not uncommon for cats to be lactose intolerant so if they eat dairy products it can cause vomiting and diarrhoea.

Raw meat

Raw meat 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.

Grape and Raisins

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.

Onions and Garlic

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 also cause anaemia.


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.
