Healthy for you… deadly for kitty

10 potential toxic foods you should never feed your cat.


Own up now if you’re guilty of slipping your cat treats every time you sit down to a meal or snack by the fridge.

While most will justify this ‘treat giving’ by handing her only ‘nutritious’ food, you may be shocked to learn that what is healthy and nutritious for you is most likely poisonous for kitty.

Here’s a rundown of 10 potential toxic foods you should never feed your cat.

1. Milk

Contrary to popular belief, cats don’t take to milk like bears to honey. Many cats are lactose-intolerant, resulting in her suffering from painful stomach upsets, cramps, and gassiness if she drinks milk.

2. Raw eggs

Apart from possibly containing Salmonella, raw eggs do contain an enzyme called Avidin, which decreases the absorption of biotin (a B vitamin). If eaten regularly, raw eggs could result in skin and fur problems.

3. Raw meat, liver & fish

Apart from the possibility of ingesting bacteria that can cause food poisoning, there is also an enzyme in raw fish that destroys thiamine, an essential B vitamin for your cat. A lack of thiamine can cause serious neurological problems and lead to convulsions and coma. Too much liver on the other hand can lead to vitamin A toxicity.

4. Canned tuna

Surprising uh? While tuna is fine as an occasional treat, eating tuna or any kind of oily fish on a regular basis has been known to result in a condition called Steatitis or Yellow Fat Disease, a very painful condition that if not addressed immediately could result in the death of your cat.

5. Chocolate, coffee, tea

She doesn’t know any better, but don’t give in. 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). When ingested, these chemicals act as a diuretic, causing the body to lose fluids or act as a cardiac stimulant, causing your cat’s heart to race. It is also a central nervous system stimulant.

6. Onions, garlic & other related root vegetables

Essential in our cooking, but really bad for kitty. Onions contain N-Propyl Disulphide, a substance that can destroy red blood cells in your cat, causing a form of anemia called Heinz Body Anemia. Garlic contains a similar substance but in a lesser amount.

7. Mushrooms

Some mushrooms are toxic to humans and many kinds that you can eat, your cat shouldn’t. Once ingested, the toxins could affect multiple systems in her body, cause shock, or in a worse case scenario even death.

8. Green tomatoes & raw potatoes

These foods are members of the Solanaceae family of plants, which includes the Deadly Nightshade, and contain a bitter, poisonous alkaloid called Glycoalkaloid Solanine. This alkaloid can cause violent lower gastrointestinal symptoms. The leaves and stems are particularly toxic.

9. Grapes & raisins

Delicious to us, deadly to her. These have been known to cause kidney damage. The active ingredient hasn’t been identified but even in small amounts, some cats can fall ill.

10. Apricot seeds/pits, cherry, peach pits, almonds, apple seeds, Avodaco fruit/pit

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 your cat will suffocate while her blood is full of oxygen.

A toxin known as Persin 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.

Others – eggplant, tobacco, elderberry, salt, soy & rice bran, hops, fat trimmings and bones.
