If your cat suddenly loses interest in food and would instead sleep all day, it could be a sign of poisoning. Cats love food, and if your feline friend is uninterested in eating, it’s time to take them to the vet.


Seizures occur when there’s abnormal electrical activity in the brain. If your cat is experiencing seizures, take them to the vet immediately. Symptoms may include muscle twitching, collapsing, or uncontrolled shaking.


Cats that have ingested poisonous substances may experience nausea, which often results in excessive drooling and swallowing. If your cat is restless, they may also lick their lips or appear to gag frequently.

Lethargy is characterised by a lack of energy or enthusiasm to do anything. Cats may often prefer to lie down or stay still rather than moving around, which can be caused by a variety of factors, including poisoning.

Rapid Breathing and Heart Rate

Cats that have ingested toxic substances will often exhibit rapid breathing and heart rate. If you notice your pet’s breathing rate is considerably faster than their normal rate, take them to the vet as soon as possible.

In this blog post, we will discuss the impact of toxic food on cats’ organs, including kidney damage, liver damage, heart failure, central nervous system damage, and gastrointestinal issues.

Heart failure

Central Nervous System damage

  • Some human foods can contain toxins that are harmful to a cat’s central nervous system, leading to nerve damage and neurological disorders.

Treating Poisoning in Cats

Cats are known for their curious nature, but this can sometimes lead them into trouble. One potential danger that cat owners must be aware of is poisoning from human food, which can be fatal if left untreated. In this post, we’ll focus on the various ways to treat poisoning in cats.

Induced Vomiting

Inducing vomiting can be effective in removing toxic substances from a cat’s stomach. It should only be done under the supervision of a veterinarian, who will determine the appropriate dosage of medication to use. Some key points to remember include:

  • Only induce vomiting within the first two hours after the cat has ingested the poison
  • Do not use salt or ipecac syrup to induce vomiting, as they can be harmful to cats

Gastric Lavage

Gastric lavage, also known as stomach pumping, involves washing out the cat’s stomach to remove any remaining poisonous substances. This is a more invasive procedure that requires anesthesia, and should only be done by a licensed veterinarian. Here are some important considerations for gastric lavage:

  • It is typically only done in severe cases of poisoning
  • The cat may need to be monitored for some time afterwards to ensure there are no complications

Activated Charcoal

Activated charcoal can be used to absorb toxic substances in a cat’s digestive system. It is administered orally, but must be given within a specific timeframe to be effective. Here are some things to know about activated charcoal:

  • It is most effective when given within an hour of the cat ingesting the poison
  • It can cause constipation, so the cat may need to be given a laxative afterwards

Fluid Therapy

Fluid therapy involves administering fluids to the cat to help flush out the poisonous substance. This can be done through an IV or subcutaneously (under the skin). Here are some key points to remember about fluid therapy:

  • It helps to prevent dehydration and kidney damage from the poisoning
  • The type and amount of fluid administered will depend on the severity of the poisoning

Medications for Various Symptoms

Depending on the specific symptoms the cat is experiencing, medications may be prescribed to treat them. For example:

  • Antihistamines can be used to treat allergic reactions
  • Anti-seizure medications may be given if the cat is experiencing seizures
  • Pain medication may be prescribed if the cat is in pain

When to seek Veterinary help

Cats are curious creatures, and they have a habit of eating anything that smells or looks interesting. Unfortunately, not everything that’s safe for humans is safe for them. Some human foods contain toxins that can quickly cause sickness or even death in cats. It’s crucial to be aware of which foods can be dangerous and to seek veterinary help as soon as you notice any signs of illness. In this article, we’ll discuss when to seek veterinary help if your cat has ingested toxic human food.

Immediately Going to the Vet

Time is of the essence when it comes to toxic reactions in cats. If you suspect that your cat has ingested something toxic, you need to act fast and take them to the vet immediately. Signs of poisoning can include vomiting, diarrhea, lethargy, seizures, and trouble breathing. However, some toxins may not show symptoms for hours or even days, so it’s better to err on the side of caution and seek immediate veterinary attention.

Life-Saving Measures That Must be Taken at Home Before Going to the Vet

While you’re on your way to the vet, there are some life-saving measures you can take at home to help your cat. If your cat has vomited, make sure to clean it up to prevent them from re-injuring themselves. You can also flush your cat’s mouth with water to remove any traces of the toxic substance. However, make sure not to force water into their throat, as it could cause them to choke. It’s also important to keep your cat warm and quiet during transport to the vet.

Urgent Signs to Look for Before Rushing to the Vet

Some signs may require urgent attention even before you can transport your cat to the vet. For instance, if your cat is having trouble breathing or has lost consciousness, you need to seek emergency vet care immediately. Another urgent sign is having difficulty standing or walking, which can indicate nerve or muscle damage. If your cat’s pupils are dilated or if they’re having seizures, these can also be signs of severe toxicity.

In conclusion, it’s important to keep your home clear of any human foods that can harm your cat, and to seek veterinary help immediately if you suspect your cat has ingested something toxic. Remember, preventing the problem is easier than treating it, so be vigilant about your cat’s diet, and keep toxic substances out of their reach. If you notice any signs of illness or toxicity, don’t hesitate and take your cat to the vet as soon as possible.
