List Of Foods Bad For Cats

Our cat friends prefer our food rather than their own. They like to jump and eat whatever they find. Unfortunately, the food we prepare for ourselves may not be suitable for them. However, not every meal is beneficial to them, and it can cause some harm to our loved ones. Here’s a list of bad foods that cats shouldn’t eat:

Tuna fish

Don’t feed your cat with tuna. Canned tuna fish prepared for humans does not have many nutrients necessary for feeding your cat. Besides, the cat’s overeating tuna can lead to mercurial poisoning in the cat.


The cat who experiences caffeine poisoning becomes restless, breathing rapidly, heart palpitations in the cat, and muscles tremble. Therefore, the cat should not give coffee, cocoa, and chocolate.

Chocolate can cause fatal consequences for cats. All kinds of chocolate contain a toxic substance called theobromine. The most dangerous types of chocolate for cats are bitter and sugar-free chocolates. If the cats eat chocolate, the Cats ‘ heart rhythm may be distorted, trembling, seizure, and death.

Bones with fat

Food, such as bone and fat, can cause vomiting, diarrhea, and intestinal disturbances in cats. Also, a piece of bone-eating cat might have a strangulation problem.

Egg yolk

Don’t feed the cat with raw eggs. Raw egg leads to two problems for cats. Bacteria such as salmonella and E. coli in the raw egg can lead to food poisoning in cats. The second problem is the Avidin, which gets found in fresh egg whites, which can prevent the absorption of vitamin B biotin. Well, can the cat eat boiled eggs? The answer is yes. You can feed it.

Onion or garlic

Don’t feed your cat onions whether they are powdered, raw, cooked, or dried. Onion can break down the cat’s blood cells and lead to anemia. Although tiny amounts of onions do not cause serious health problems for cats, overeating onions can lead to onion poisoning. Onions and garlic also cause stomach and intestinal diseases in cats.

Milk and dairy products

Most cats can’t digest lactose. Therefore, giving milk and dairy products to the cat is harmful. If you give the cat milk and milk products, your cat may start to have diarrhea.


Food containing beer, liquor, wine, and juice contaminates the cat’s health at a critical rate. Alcohol creates the same effects in cats as in humans, but the duration of the damage is immediately visible in cats. Only two teaspoons of whiskey can put the cat in a coma.

Grapes and raisins

The cause is not so obvious, the problem of kidney failure can occur in a cat who eats raisins and grapes. If the cat eats grapes, they may vomit or develop hyperactivity. Keep grapes and raisins out of the reach of cats, even if they do not harm each cat.

Raw meat and raw fish

Don’t feed the cat with raw meat and fresh fish. As with eggs, raw meat and fish can contain bacteria that will poison the cat. Besides, an enzyme in raw fish damages thiamine, a vitamin B required for the cat. Thiamine deficiency in cats can lead to serious neurological problems, resulting in a coma.

Dog food

It is not harmful to the cat to eat a piece of dog food. Dog food, however, does not replace cat food. Cat food has similar ingredients with dog food, but cat food contains more protein as well as vitamins and fatty acids. The cat regularly eating the dog food becomes severely malnourished.

Sugar and gum

You should not give your cat anything sweetened with xylitol. Xylitol gets found in toothpaste, sugar, glue, and baked goods. Xylitol leads to an increase in circulating insulin in the body and leads to a decrease in the blood sugar of the cat and liver failure. Make sure that your cat exposed to xylene is experiencing vomiting, drowsiness, and loss of attention. Liver failure disease takes only a few days to settle in the body.


It’s not a problem for a cat to eat a small amount of liver. However, if the cat eats a lot of liver, it can be vitamin poisoning. Vitamin A poisoning severely affects the cat’s bones. Symptoms of vitamin A poisoning include deformed bones, elbow, and shoulder bone growth, and bone melts. Also, vitamin A poisoning in cats can lead to death.

Bread dough

Before cooking, the mixture begins to swell with the effect of yeast. That’s precisely how it can happen in your cat’s stomach. The swollen bread dough in the belly of the cat can stretch the abdomen and cause severe pain. It can also produce alcohol that can cause alcohol poisoning in the yeast cat that interacts with the dough.


FAQ Foods Bad For Cats

How can I tell that my cat does not tolerate its food?

There are food intolerances that can be getting recognized after a short time. For example, if the cat regularly vomits after feeding a particular product, it gets diarrhea or hardened feces.

Bone metabolism disorders can develop as a result of calcium deficiency. In adult animals, this may take months or years and is not getting indicated by symptoms such as a dull coat or weight loss.

What are the harmful filling materials in cat food?

Cats are pure carnivores. Vegetables, rice, cereals, fruit, soya, or similar are not part of their diet.

Is the meat in cat food is a beneficial ingredient?

Meat means; muscle meat, but unfortunately also udder, gullet, ground cow skin, lungs, connective tissue, and everything that is not getting permitted for human consumption. It makes a big difference whether the cat food consists of high-quality muscle meat or inferior leftovers from social food production. Nevertheless, on the packaging, both are labeled as meat. Pay attention to a high meat content, at least 80%. Choose food types where the meat used is precisely declared. In this way, you can also see whether it is muscle meat or inferior meat.

Why should cats not eat vegetable by-products and cereals?

Vegetable by-products and cereals mean waste products from the human food industry, e.g., crushed peanut shells, cereal waste, wheat gluten, soya, flours, lignocellulose, sugar beet pulp, rice.
