Over the course of human history, and throughout populations migrations from country to country if not from one continent to another, humans have had to adapt to living conditions that may have not been entirely familiar to them when they first arrived in their newly adopted foreign land.  One such adjustment they need to make was the food they now ate.

Over time and with the industrial revolutions bringing with it far reach reaching consequences for our species, human have been more and more exposed to different cultures, and cuisines… Fast forward to today, and in most cities throughout the world, one could wake up in the morning to an English breakfast for example, have Italian pasta for lunch and then finish the day at a Chinese restaurant sampling the culinary marvels of yet another culture. By in large, we, as a species have adapted very well to a large variety of food.  But what about our pets? Can their metabolism cope with the multitude of different types of food, we, humans test ourselves with? Are there any food at all, that pets should keep away from? How do you keep your pet healthy?

Here are 5 foods that we shouldn’t give our cats:


Not a food they must avoid at all cost, as some tuna here and there won’t probably pose a problem, but tuna as a staple food for our felines eating habits isn’t a good idea. We’re not talking about fresh tuna here, but the kind made solely for human consumption, packaged in cans or plastic containers and which, invariable can lead to malnutrition because they lack the necessary nutritional ingredients our cats need. And of course, there is the mercury content which can be outright dangerous for cats and humans alike.

Onions, chives, garlic

You may love the taste of garlic in your Bolognese sauce, or chives and onions in your evening salads, but the onion family, powdered, cooked, raw or dehydrates is known to destroy red blood cells in cats, bringing with their breakdown the onslaught of anemia. Onion poisoning is definitely now words you’ll want to hear from your vet next time you bring your cat in because he or she may feel ill.


I know. Sounds unbelievable, and even though we’ve been told milk is good for us, ergo it’s also good for cats, it is important to remember that most cats are lactose-intolerant.  So, no milk, or even cheese for our meowing friends, because those lovely creatures cannot process dairy food.


No… Not even wine. A definite no-go. This one sounds like a no brainer, but it’s worth mentioning because alcohol has the same effect on cat’s liver and brain than it has on us. The difference I that while it takes large quantities of alcohol to impact human health, only two teaspoons of scotch whisky can cause a healthy 5-pound cat to fall into a coma.  One more teaspoon might just kill it. You know how much your cat weights… You do the math.

Grapes and raisins

Maybe it’s the sugar, nobody really knows why,  but for cats, consuming grapes and raisons can cause kidney failure and it only takes a small quantity for some to fall ill. If you catch your cat vomiting and you know he or she has just eaten grapes, then you’ll know why your little fellow is trying very hard to bring everything back. Not all cats have an adverse reaction to drapes and raisins, but it’s a good idea not to leave them around, just to find out that they do.


Caffeine is known to cause heart palpitations in humans so can you imagine the effect it might have on a cat?

As a general rule, a good idea is to visualize a cat going about the business of looking for food in nature. Take this imaginary trip in your mind, follow your cat wondering in a field with fruits and vegetables. Would he likely jump up with joy and excitement at the sight of grapes? Would she run to a milk cow dreaming about the milky nectar of goodness we have all been taught to believe it is? It is likely that the type of food our cats would naturally select for themselves would be entirely different than ours.

If you ever have to deal with a situation where you suspect your cat may have fallen ill due to something he or she might have eaten, don’t try to guess what it is that she ate.  Take her to the vet and let her find out what’s causing our furry friend to vomit all of a sudden.  In many cases, the foods that cause our cats to fall ill are taken in small quantities so as not to affect their health permanently.
