12 Foods You Should Never Give to Cats

Does Minnoş curl up next to you in the kitchen and give “a little for me too” looks while cooking? Most of us think sharing a bite at that moment is harmless — but some foods are toxic at fatal levels for cats. Hundreds of cats in Turkey are taken to emergency every year because of “a piece of cheese” given by their owners with good intentions. Here are 12 foods you should never give to your cats and the scientific reasons.

1Onion and garlic — destroys cat’s red blood cells.

The substance “n-propyl disulfide” found in onion and garlic causes oxidative damage in cats’ red blood cells, breaking them down and leading to Heinz body anemia. Even very small amounts are dangerous — a tablespoon of cooked onion can reach toxic dose for a 4-kg cat. Being cooked doesn’t ease the situation; onion powder is more concentrated. Don’t share menemen, soup, stews.

2Chocolate — theobromine is a deadly toxin.

Theobromine and caffeine raise heart rates in cats, can lead to seizures and death. Dark chocolate is 10 times more dangerous than milk chocolate. 30 grams of dark chocolate is critical dose for a 3-kg cat. Symptoms start within 2-4 hours: vomiting, tremor, restlessness, rapid breathing. If cat shows these symptoms, immediately to vet — activated charcoal and supportive treatment essential.

3Grapes and raisins — kidney failure risk.

Why grapes and raisins cause kidney failure in dogs and cats is still unknown — but in many cases the result is fatal. Even a handful of raisins is dangerous for your cat. You need to check raisins in cake, muffin, dessert mixes. Aşure, dolma and pilaf with raisins beloved by Turkish cuisine — should never be given to cat.

4Milk and dairy products — lactose intolerance.

The cliché “cats love milk” is wrong. 85% of adult cats carry lactose intolerance. When given milk, diarrhea, abdominal bloating, gas and vomiting are seen. Due to children’s books and cartoon image, milk is thought harmless but cat’s digestive system can’t break down milk sugar. Special-formulated “cat milk” products exist — not regular cow milk.

5Raw meat and raw eggs — Salmonella and E. coli risk.

While BARF (raw meat diet) gains popularity, uncontrolled application at home creates bacterial infection risk. Salmonella, E. coli and Listeria can devastate cat’s digestive system. Also avidin protein in raw egg whites blocks vitamin B (biotin) absorption. Must be cooked and fresh — raw meat left on street should not be touched.

6Bones — especially cooked bones.

Cooked bones become brittle with heat treatment, splitting into small pieces that pierce esophagus, stomach and intestinal walls. Chicken and fish bones are especially dangerous. Even raw large bones, if given without supervision, carry choking risk. Cat needs muscle meat — not bones. Should never be given as food scraps.

7Tuna fish — long-term consumption causes mercury poisoning.

Constantly giving with the thought “my cat loves tuna” is a big mistake. Tuna accumulates mercury because it’s high in food chain. Constant consumption can lead to mercury poisoning, vitamin E deficiency and “yellow fat disease” inflammation of fat tissue. Small portion 1-2 times a month harmless; daily consumption dangerous. Salty tuna cans produced for human consumption not appropriate at all.

8Avocado — persin toxin.

Avocado pit, skin and leaves contain a toxic substance called “persin.” While its effect on cats is not as severe as on dogs, it can cause vomiting, diarrhea and in some cases cardiac problems. Toast, salad, guacamole — plates cats shouldn’t approach. No safe dose; zero consumption recommendation valid.

9Alcohol — fast absorption, serious poisoning.

Letting lick beer foam, giving drop of raki — all dangerous. Cat’s liver can’t break down alcohol; even 2-3 ml of alcohol reaches poisoning dose for 4-kg cat. Symptoms: loss of coordination, vomiting, tremor, coma. Alcohol in dough (uncooked bread dough produces alcohol during fermentation) is hidden threat. Keep dough away from cat.

10Raw onion family — leek, scallion, shallot.

All members of the Allium family (onion, garlic, leek, scallion, shallot) are toxic to cats. Leek is especially common in Turkish cuisine; meat dishes with boiled leek shouldn’t be shared. Versions in onion powder form (soup base, fast food spice) are more concentrated. Sharing ready soup is dangerous because of this — check content label.

11Caffeine — tea, coffee, energy drinks.

Caffeine seriously disrupts cats’ heart rhythms, leads to seizures. Even a sip of coffee dangerous for small cat. Turkish coffee and brewed tea especially contain high caffeine. Drop of energy drink fatal. Even leaving coffee cup on desk is risk — cats can curiously approach and exhibit tasting behavior.

12Xylitol — hidden poison in diet foods.

Xylitol found in sugar-free gum, diet sweets, some peanut butters and sugar-free sodas; creates sudden blood sugar drop and liver failure in cats. Already known danger in dogs has been confirmed in cats by current findings. Build the habit of reading labels; “sugar-free” products should stay away from your cat.

As final words,

Although cats appear selective eaters, they actually make mistakes from curiosity — they don’t stop chasing a poisonous onion slice that takes their breath. Responsibility is on the owner. Keeping these 12 foods away from your kitchen or at least storing them on high shelves eliminates nights at vet emergency door. When you see suspicious consumption, immediately consult your vet — early intervention can save your cat’s life.
