20 Foods That Harm A Maine Coon Cat

Do you know the foods not to give Maine Coon cats? If you don’t then stop feeding your Maine Coon without knowing how certain foods can affect them.

There are some common foods and ingredients which you need to look out for so that your Maine Coon does not lay their paws on them. Foods like dairy, onions, garlic, raw eggs, raw meats, chocolate, alcohol, can be extremely toxic to your cat.

You may be tempted to give your Maine Coon table scraps and special treats. But a little reward from the table can hurt your Maine Coon a lot.

So, before you feed your Maine Coon something other than the cat food, check this list once to make sure it is safe for your cat.

Foods Not To Give Your Maine Coon Cat

Many human foods can be dangerous to your Maine Coon’s health and at the same time deprive them of the essential nutrients they can get from good premium cat foods.

These extra foods and treats can zap their appetites for their regular meals also.

A sliver of chicken, or turkey won’t kill your cat, but you will be helping them develop bad habits.

Some foods when fed in smaller quantities may not cause a problem but larger quantities may require the immediate attention of a vet.

Here we have put together a list of 20 foods that can be dangerous and even potentially fatal for your Maine Coon cat.

Most of the cats are known to be picky eaters which make us assume that they know what is best for them. But that is not true.

Indeed, whilst your cat will not eat people’s food gluttonously as a dog however that does not mean your cat will never partake in some human food.

There are some common foods your Maine Coon should never eat which can make their stomachs whirl.

The following foods should be best kept away from your Maine Coon cats entirely:

1. Chocolate

Chocolate can be poisonous for your Maine Coon.

Chocolate consists of substances called methylxanthines which can cause symptoms like:

  • High body temperature
  • Vomiting
  • Diarrhea
  • Increased thirst
  • Seizures
  • Abdominal discomfort

Darker chocolates can be more fatal than milk and white chocolates.

2. Alcohol

Alcoholic beverages can be very dangerous for your cat.

Their ingestion can cause tremors, vomiting and diarrhea, trouble breathing, and even death.

Any beverage containing alcohol like beer, wine, liquor, or even foods containing alcohol is not good for your cat.

Just a few licks of alcohol can cause bigger problems in your cat.

3. Milk And Dairy Products

Your Maine Coon may enjoy having milk and other dairy products like cheese but it isn’t good for them.

Most cats are lactose-intolerant and Maine Coons are one of them.

Cats cannot digest the lactose in the milk which can lead to an upset stomach and other digestive issues.

All the kittens have lactose from their mother’s milk for a few weeks after birth and their digestive system is most often not capable of handling lactose again and finds it difficult to process dairy products also.

4. Raw Meats

Just because cats in the wild eat raw meat does not mean your domesticated Maine Coon can also be given raw meat.

Uncooked meat is not safe for your cat and can make your cat ill.

Raw meat is more likely to contain harmful bacterias like Salmonella and E.coli and even tapeworms which can cause many life-threatening diseases in your cat.

5. Sugary Products

Sugary products do not give any nutritional benefit to your Maine Coon.

Certain sweeteners like xylitol are found in candies and other sweetened foods and can cause your cat’s blood sugar to drop and also lead to liver failure.

6. Fish

Maine Coons can get hooked to fish especially tuna.

A little bit of tuna won’t hurt but too much tuna prepared for humans can cause malnutrition in your cat.

Besides, too much tuna can lead to mercury poisoning also.

7. Gluten

Cats develop intolerances and allergies to gluten in many cat foods. Intolerance to gluten can cause diarrhea and vomiting.

8. Onions And Garlic

Onions and garlic can cause anemia in your Maine Coon by damaging their red blood cells.

These foods whether they are consumed in large quantities or in concentrated forms like garlic powder or onion soup mix are toxic.

9. Grapes And Raisins

A small amount of grapes and raisins is enough for your Maine Coon to develop kidney failure and make your cat ill.

Some of the early symptoms are incessant vomiting and hyperactivity. Other symptoms that can show up within 24 hours of ingestion include:

  • Abdominal Pain
  • Diarrhea
  • Decreased Urination
  • Reduced Appetite

10. Raw Eggs

Raw eggs can cause food poisoning in cats as they contain harmful bacterias such as Salmonella and E.coli.

The other reason is that raw egg whites contain a protein called avidin which could interfere with the absorption of vitamin B.

As a result, this can lead to skin problems in your Maine Coon.

11. Coffee Or Tea

Caffeinated drinks like coffee and tea can cause tremors, troubled breathing, increase heart rate, seizures, and hyperactivity in cats.

12. Mushrooms

Mushrooms contain a number of toxins and can cause symptoms like:

  • Drooling
  • Vomiting
  • Diarrhea
  • Liver damage

A small number of mushrooms won’t harm your cat but certain varieties of mushrooms are extremely toxic and therefore it is better to be safe than sorry.

13. Human Medicines

Consumption of human medicines is the most common cause of poisoning in cats.

Any over-the-counter medicines should not be given to your Maine Coon unless recommended by your vet.

Some common pain relievers and cold medicines can be fatal for your cat.

14. Avocados

Avocados are extremely rich in fiber, monounsaturated fats, vitamins, and minerals.

But, because of their high-fat content, you should be careful about how much you feed them to your Maine Coon.

Avoid feeding the peels also as they may contain toxins.

15. Nuts

Nuts are an incredible source of healthy fats, fiber, and protein but you should be careful when feeding them to your Maine Coon.

Macadamia nuts are dangerous for cats but other nuts like almonds, and walnuts are not inherently poisonous.

16. Dog Food

Dog food is not dangerous for your cat. But your cat’s nutritional requirements are different than a dog.

Cats need higher levels of vitamin A and protein. Whereas dogs can survive without these.

Cat food should consist of taurine, arachidonic acid, vitamin A, and lots of protein.

Without enough taurine in their bodies, cats can develop a vision and dental issues and even heart diseases.

17. Baby Food

Baby food may contain meat seasoned with onion and garlic, and so shouldn’t be fed to your cat.

18. Bones And Fat Trimmings

Fat trimmings and bones can both be bad for your Maine Coon.

Tidbits from your food whether cooked or uncooked contain fat trimmed from bones and meat and can cause an upset stomach along with vomiting.

Your Maine Coon could also choke on a bone and the splinters on them can injure your cat’s digestive system.

19. Liver

The liver is a great source of iron, protein, and other nutrients your cat needs for its overall health and wellbeing.

But excess of vitamin A can be too much of a good thing.

Feeding too much liver for long can cause a condition called hypervitaminosis A, in which there is an excessive buildup of vitamin A causing toxicity.

20. Yeast Dough

The yeast present in loaves of bread and pizza doughs can very quickly produce a sufficient amount of alcohol and carbon dioxide to cause problems for your cat.

Moreover, the dough can also rise inside your cat’s tummy to a size that may sometimes need surgery to remove the digestive obstruction.

The Best Diet For Maine Coon

A Maine Coon is a big cat and therefore needs a lot of energy to fuel their bodies. Most importantly, they need a meat-based diet.

The best diet for a Maine Coon includes good quality dry food, and an occasional mix of wet and dry maybe 2 to 3 times a week.

The dry food should be devoid of grains, as they can cause obesity in your cat.

It is a matter of preference whether you feed your Maine Coon dry or wet food.

Dry food can help your cat use their teeth. Wet food is high in moisture and so can keep your cat hydrated also.

A mix of both wet and dry can give the right balance to your cat.

Remember to feed your Maine Coon the diet that meets their nutritional requirements as per their age.

Foods high in moisture containing animal-based protein and low in carbohydrates can be great for your Maine Coon.

Feed your cat real meat and no by-products.

Maine Coons naturally drink a lot of water and therefore should have access to freshwater all the time.

Your Maine Coon’s diet should be nutritionally balanced and should consist of the following elements:

1. Protein

Proteins provide your cat with amino acids required to build tissues. Animal protein gives a lot of essential amino acids to your cat.

2. Fats

Fats can also provide your Maine Coon cat with essential fatty acids to help keep their fur and skin shiny and healthy.

3. Carbohydrates

Carbohydrates give your cat energy however a cat’s body is designed for a low-carbohydrate diet.

Your cat’s body cannot produce the enzymes required to process a lot of carbohydrates.

4. Vitamins And Minerals

Your cat needs vitamin A and vitamin B because their bodies cannot produce these vitamins on their own.

Both vitamins and minerals are required to support many of the body’s normal chemical reactions.

5. Water

Water is essential for your Maine Coon’s normal body functions and helps their bodies absorb important nutrients.

Why Is My Maine Coon Always Hungry?

A perpetually hungry cat can make you go nuts.

A cat begging for food by meowing incessantly and climbing onto the kitchen counters can be frustrating.

Maine Coons are high-energy cats and that is the primary reason behind their fast metabolism.

If your Maine Coon demands food all the time there may be other reasons such as intestinal worms, digestive problems, or insufficient diet.

1. Worms

Your cat may have worms because the worms take away all the nutrition from their food leaving your Maine Coon hungry most of the time.

So, if you suspect your cat has worms take a fecal sample to your vet to have it tested.

2. Diabetes Or Hyperthyroidism

Both diseases can increase your cat’s appetite exponentially.

Hyperthyroidism spikes the appetite as your cat’s metabolism burns too many calories.

If your cat has diabetes then their body cannot convert sugar to energy and the nutrition in their food is not able to get to their bodies.

Other symptoms related to these conditions could be excessive thirst and loss of weight. A vet should be consulted as soon as possible.

3. Food Not Meeting Their Nutritional Needs

Feeding poor-quality cat food cannot satisfy your Maine Coon’s hunger for nutrients.

Felines bodies are made mainly for meat and not grains. Therefore ensure there is enough meat in their diet.

4. Regurgitation

Sometimes after having eaten their foods, cats vomit out the whole food without adequately chewing it. This is called regurgitation.

Many medical problems can cause regurgitation in your Maine Coon including problems with the esophageal tract or the throat. A thorough diagnosis can determine the problem.

5. Pregnancy

If your Maine Coon is pregnant their demand for food will surge to make room for the kittens’ nutrition inside their wombs.


There are a number of “people foods” that your Maine Coon shouldn’t eat at all. Sometimes only a nibble can be fatal to their health.

Once in a while, you can give your Maine Coon a treat from your plate.

But, it would be best to stick to high-quality cat food only and stop feeding anything else to protect your furry friend’s health!

Hello! My name is Katrina Stewardson, and I’m a CRAZY CAT LADY! I've been in love with the Maine Coon cat breed ever since we welcomed an adorable male Maine Coon kitten into our home 10 years ago. We called him 'Pippin', but he also goes by the name ‘Pipsteroo’! Our enormous, kind-hearted cat genuinely thinks he's a dog and has convinced me that cats are Man's True Best Friend! UPDATE: We recently adopted two 4-year-old male Maine Coon cats. They are named Mika and Bali.
