‘Dubious’ foods to feed a cat

Some human foods can be fatal for cats

Raw meat and fish

Giving our cat fresh food is an option with two faces, one positive and one negative. On the one hand, it is true that it is the best way for them to be nourished, since this type of food favors a maximum use of their nutrients, since their digestive system is capable of digesting uncooked food in an optimal way.

However, your entire diet should not be framed in this type of diet, measuring the amount is essential because, in the specific case of fish, there are some types that subtract vitamins instead of adding them. On the other hand, you must be especially careful with raw foods due to toxoplasmosis in the case of meat and anisakis in fish, try to make sure they are pieces of meat or fish that have gone through a freezing phase to kill them.


You may think that sausage is not too bad food for your cat, after all it is meat. However, depending on the piece, it is generally ultra-processed with high levels of salt, which can cause serious kidney problems in the cat if it is eaten regularly.

Serrano ham, cooked ham, and sausages may have salt levels well above what is recommended , but they may also contain sugar, specifically fuet and other sausages and chorizos, which can cause health problems for your cat. since sugar is a banned nutrient for him.

Pastries and cookies

Both pastries and cookies for humans contain sugar, which makes them unhealthy foods for a cat since they do not digest this nutrient well. On the other hand, if you wonder if they can digest the flour used for these preparations, in this case the answer is yes, but the flour does not provide any useful nutrient for them and can trigger obesity, or at least speed up a process.

Of diabetes. The smell of these foods will interest them, also because they have certain yeasts in common that can be used for cat biscuits, and they may believe that it is this type of snack.

Grapes and raisins

As they are very innocuous fruits, we might think that both grapes and their dehydrated version such as raisins might not be harmful to cats, however this is not the case. Eating grapes or raisins for a cat can be a serious problem that triggers kidney failure.

If your cat eats this food by mistake, you may need to contact your vet. Although it does not always happen, statistics have shown that a large number of cases in which cats eat these fruits develop kidney and liver problems, there is a specific substance in grapes that is toxic to them, and in its dehydrated version it is toxicity is multiplied by 4.


This fruit, high in potassium and vitamins, is not very appreciated by cats, generally they will not chase you to give them a piece of banana or plantain.

However, in moderation it is not bad to give them a little piece, if they feel like it, although in general it can be harmful to their health due to its high glucose content. If they eat more than one piece, the first consequence they will have will be diarrhea.

Fish entrails

The viscera of the fish contain what are called anti-nutrients that act on the cat’s vitamin reserves, destroying certain vitamins, specifically it usually affects B1, which is very serious because it is essential for its mobility, agility and flexibility.

A diet that is abundant in fish entrails can cause the cat to develop rigidity in its muscles and eventually even suffer paralysis.

Raw eggs

Although we think that there is nothing more natural than a raw egg, the truth is that the eggs that are consumed produced in intensive farms differ a lot from the eggs from an idyllic farmyard, there are many parasites that can have if they are not cooked properly, and these affect both humans and animals.

Cats are also sensitive to a substance in the egg called avidin , which is an antinutrient that produces an adverse effect on the animal: what it does is subtract the general absorption of vitamin B.

Reserve cans

The levels of salt in canned food are acceptable for the health of humans but are in serious conflict with cats, it is a lot of salt for their kidneys and eating this food time can cause kidney failure sooner rather than later. the animal.

Even so, you may think that a can of natural tuna may be perfect for the cat, but it also has a high content of it. It is best to give it fresh tuna (although thawed to get rid of the anisakis), since the canned one also has preservatives.


Not only should you not give your cat citrus, it is also that it will be absolutely impossible for him to get him near any of these fruits and even bring his muzzle close.

Cats hate citrus fruits, be they oranges, lemons or anything else. But it is that, in addition, they are toxic fruits for which they feel a natural aversion. The fault lies with an essential oil, linalool, which, when ingested by the cat, can affect its central nervous system, as well as cause strong stomach irritation.
