As we know, Low quality commerical cat food can also be harmful for your cat’s health. However, This is a list of human foods that you should never feed your cat to prevent their digestive system and general health depriciation.
Raw Protein Sources
When it comes to what can cats not eat, You should know this on top of your head. Any raw protein source fed to your cat imposes a risk on its life. This is because raw foods contain a high amount of active microorganisms. Those of which are usually eliminated during the cooking process.
1) Raw Red Meat
The most common microorganisms in raw red meat include Listeria monocytogenes, and Staphylococcus aureus. Don’t get scared by the names. Let me explain: Raw meat can cause vomiting and diarrhea, followed by muscle stiffness and convulsions. Such situations, when not treated urgently, can be fatal. Also, Listeria is not common among cats but can cause severe complications in your cat’s body.
2) Raw Chicken and Raw Eggs
Raw eggs and chicken contain microorganisms like Salmonella, Campylobacter, and E.coli. All these microbes induce gastrointestinal inflammation, also known as gastroenteritis. Thus showing several clinical signs that include vomiting, diarrhea, fever, and lethargy.
Onions contain an oxidant substance known as an n-propyl disulfide. This substance can cause oxidative damage to red blood cells in your cat’s bloodstream. Eventually, onion ingestion could cause a severe form of anemia.
Just like onions, they contain disulfides and thiosulphates. These might alter the ability of RBC to carry oxygen due to complications such as methemoglobinemia. This condition occurs when methemoglobin increases in blood and alters normal oxygen transfer.
Also imposes a risk on red blood cell health and might be a factor causing hemolytic anemia.
6) Wild Mushrooms
These can be highly toxic for cats. Ingestion of toxic mushrooms can cause agitation, vomiting, diarrhea, and tremors.
Tomatoes contain a substance which is known as solanine. Cats that ingest solanine will experience symptoms similar to that of poisoning. These can vary from vomiting and diarrhea to death, depending on the amount ingested.
Potatoes hold the substance solanine and thus show similar symptoms if ingested by cats.
9) Grapes and Raisins
These foods can cause serious complications among cats if ingested. It is known to be linked to kidney failure. Complications vary depending on the ingested amount.
Oranges contain citric acid and essential oils. Each of these is harmful to cats in a different way. Citric acids will irritate the stomach lining. Additionally, essential oils were related to nervous system damage. Therefore, ingestion of oranges will probably lead to symptoms of vomiting and diarrhea.
11) Cherries and Plums
While these fruits are not toxic, their pits are dangerous if consumed by cats. Cherry and plum pits contain fair amounts of cyanide, which is poisonous for cats. Therefore any slight consumption of cherry pits will cause complications. If consumed in large amounts, it will most likely cause death.
Cats are known to be lactose intolerant. Meaning that they lack the enzyme lactase that digests lactose. Thus, dairy products might cause gastrointestinal complications such as an upset stomach.
As mentioned before, ingestion of any lactose-containing substance will cause gastrointestinal discomfort. Additionally, adding milk to your cat’s diet will build on some fats your cat’s body does not need.
Again, cats cannot break down dairy products. For this reason, cheese is an unfavorable food to add to your cat’s meal.
Besides the lactose intolerance issue, ice cream can cause complications in your cat’s body due to the presence of sugars. Similar to lactose, sugar can stimulate a gastrointestinal reaction. Thus showing symptoms like abdominal pain, vomiting, and diarrhea.
Other Common Foods Toxic To Cats
Consumption of Caffeine is prohibited for cats. This is because it alters normal blood pressure and causes arrhythmias among cats. It is also known to cause gastrointestinal signs. These include an upset stomach and impaired digestion.
You have probably already heard this several times; Chocolate is highly dangerous for cats. Theobromine is one of the components found in Chocolate. This component handles a rapid increase in heart rate and promotes the loss of fluids. Both reactions can lead to fatality.
While nuts contain high amounts of essential fatty acids, they are bad for your cat’s health. Apart from the choking hazards they might cause, nuts might cause cyanide poisoning. Nuts like almonds contain cyanide and might show signs similar to potato and tomato ingestion.
Wine, Beer, or any other alcoholic drink contains ethanol. Ethanol poisoning can be fatal among cats. It causes loss of consciousness, incoordination, and in extreme cases, respiratory failure.
Chicken or fish bones are one of the most dangerous feeding materials you can serve to your cat. While bone broth is beneficial and nourishes your cat, solid bones can cause many serious complications. Improper digestion and intestinal and gastric perforations are common consequences of bone consumption. And even though your cat might enjoy chewing on some chicken bones, they impose a huge risk on its health.
Xylitol induces the reaction of a false alarm in your cat’s body. Leading to a rapid increase in blood insulin that will deplete the sugar in your cat’s blood, causing hypoglycemia. Additionally, it may cause long-term damage to organs such as the liver.
