Oysters contain a toxin called domoic acid, which is harmful to both humans and animals. When consumed, this toxin can cause vomiting, diarrhea, seizures, and even death.

Domoic acid is found in the tissue of shellfish like oysters, clams, and mussels. It’s produced by algae and can accumulate in the seafood that eats it.

While the levels of domoic acid in oysters vary depending on where they’re sourced from (wild or farm-raised), all oysters have the potential to be toxic to cats.

Cats are obligate carnivores, and as such, they need to eat meat in order to survive. Oysters are not a part of the natural diet of cats, and they do not have the digestive system to properly digest them. Feeding a cat oysters can result in serious health problems like intestinal blockages, vitamin deficiencies, and even death.

List Of Reasons Why Oysters Are Bad For Cats ?

There are several reasons why oysters are bad for cats. Here is a list of the most important ones:

1. High In Purines :Oysters are high in purines, which can cause problems for cats with kidney disease. Purines are natural compounds found in many foods, including oysters. They’re metabolised by the body and excreted in urine.

High levels of purines can lead to an accumulation of uric acid in the blood, which can cause kidney stones and other health problems. Cats with kidney disease are especially at risk for these problems.

Feeding your cat oysters can worsen existing kidney problems and lead to new ones. If your cat has kidney disease, it’s best to avoid feeding them oysters altogether.

2. Oysters May Contain Toxins: As previously stated, oysters may contain toxins such as domoic acid.These toxins can be harmful to your cat and cause serious health problems.

Domoic acid poisoning can lead to vomiting, diarrhea, seizures, and even death. If you suspect that your cat has eaten an oyster, it’s important to take them to the vet.Oysters can contain harmful toxins like ciguatera, which can make cats very sick.

3. Bacteria: Oysters may contain harmful bacteria such as Salmonella and E. coli.These bacteria can cause gastrointestinal distress and other health problems in cats. If your cat has eaten an oyster, it’s important to watch for signs of illness and take it to the vet if necessary.

Oysters can contain bacteria like Vibrio vulnificus, which can cause serious illness in cats.

It’s important to note that raw oysters are more likely to contain harmful bacteria than cooked ones. If you choose to feed your cat oysters, it’s best to cook them thoroughly first.

4. May Contain Viruses:Oysters can also contain viruses like the Norovirus. These viruses can cause gastrointestinal illness in cats.

The Norovirus is a type of virus that can cause vomiting and diarrhea in humans and animals. Norovirus is highly contagious and can make cats very ill.

5. Choking Hazard: Oysters can pose a choking hazard to cats.Cats have small throats and can easily choke on the shells of oysters.They can easily become lodged in a cat’s throat and cause suffocation.

6. Can Cause Stomach Upset: Feeding oysters to your cat may cause stomach upset.Cats have sensitive stomachs and may not be able to tolerate the high levels of purine in oysters. This can lead to vomiting, diarrhea, and other gastrointestinal problems.

Eating too many oysters can give cats an upset stomach or even lead to poisoning.

7.Can Cause Allergies: Oysters can cause allergies in some cats.The symptoms of an allergy can range from mild (rash, itching, swelling) to severe (trouble breathing, hives, anaphylaxis). If your cat has eaten an oyster and begins to show signs of an allergic reaction, it’s important to take them to the vet immediately.

Some cats may be allergic to the proteins in oysters. This can lead to serious health problems.

Will Eating Oysters Kill A Cat?

Eating oysters will not kill a cat outright, but it can lead to serious health problems that can be fatal. That’s because oysters can contain harmful bacteria that can cause food poisoning.

Symptoms of food poisoning in cats include vomiting, diarrhea, and dehydration. So if your cat eats too many oysters, they might end up feeling really sick – and could even require a trip to the vet.

Symptoms of PSP poisoning in cats include muscle tremors, paralysis, and respiratory failure. Symptoms of domoic acid poisoning in cats include vomiting, diarrhea, seizures, and coma.

If you think your cat has eaten oysters and may be experiencing any of these symptoms, please contact your veterinarian immediately.

What To Do If Your Cat Has Consumed Excessive Oysters?

Cats are generally pretty resilient creatures and can handle eating things that we humans wouldn’t dream of consuming. So, unless your cat is showing signs of being unwell, there’s no need to panic.

If your cat has consumed excessive oysters, the first thing you should do is call your veterinarian. They will be able to advise you on what to do next and whether or not your cat needs to be seen by a professional.

Here is a list of things you can do at home to help your cat :

  • Keep Them Hydrated :First, make sure they stay hydrated by giving them plenty of fresh water to drink. You can also give them some Pedialyte or Gatorade to help replenish their electrolytes.
  • Give Them Bland Food : Second, give them some bland food like boiled chicken or rice to help settle their stomach.
  • Monitor Them Closely : Lastly, monitor them closely for any changes in their behavior or appearance. If they seem to be getting worse, please take them to the vet right away.

When To Take Your Cat To The Veterinarian?

If your cat has consumed a large amount of oysters or is showing signs of being unwell (e.g. vomiting, diarrhea, lethargy), it’s important to take them to the veterinarian right away.

The vet will be able to determine if your cat is suffering from food poisoning and will provide the appropriate treatment. In severe cases, hospitalisation may be required.

While most cats will only have mild gastrointestinal symptoms after eating raw oysters, such as nausea or diarrhea, more serious problems can happen, such as intestinal blockages and even death, if they eat them.

So if you notice that your cat has eaten a lot of oysters – especially if they seem to be having any digestive issues, it’s best to seek professional help.
