can a cat have aspirin

Cats have fewer functional cellular pathways to metabolize certain types of drugs, including aspirin. This means they take significantly longer to eliminate salicylates from their bodies than humans or dogs. Since cats are not able to metabolize aspirin efficiently, they are more vulnerable to poisoning.

Symptoms and Types of Cat Aspirin Toxicity

The progression of symptoms can occur quickly. Loss of appetite is often one of the earliest symptoms to be apparent.

Other symptoms of aspirin toxicity in cats include diarrhea and vomiting, which are caused by stomach and small intestine ulcers. There could be fresh blood (red) or digested blood (dark brown to black) in the vomit or diarrhea.

It’s also possible for the central nervous system to be impacted, which could lead to your cat collapsing, having problems walking, or appearing weak and uncoordinated. Loss of consciousness and sudden death can also occur.

When giving your cat aspirin that has been prescribed by a veterinarian, it is crucial to keep an eye out for any digestive issues or behavioral changes because even when given in the recommended dosage, aspirin for cats can cause these symptoms.

In the event that a sizable quantity of aspirin is consumed, immediate medical attention is required.

If your cat is exhibiting telltale signs of toxicity and you know or even suspect that it may have ingested aspirin, call an emergency veterinarian right away.

The goal of diagnostic testing should be to ascertain how toxic the substance is. A complete blood count, a urinalysis, and a chemical blood profile will all be part of the blood profile procedure.

Often an affected cat will be anemic (low red blood cell volume) with electrolyte abnormalities, in addition to showing a reduction in the bloods ability to clot properly. Aspirin reduces blood flow to the kidneys, which can cause or worsen existing kidney disease.

If cats are treated within 12 hours of ingestion and show only mild symptoms of distress, a prescribed decontamination treatment can lower the aspirin concentration in their bodies. The sooner this care begins, the better.

Your veterinarian might advise you to induce vomiting at home before visiting the clinic, or they might do it there. This would reduce the amount of aspirin in the body.

Your veterinarian will be able to extract as much aspirin as possible by inducing vomiting or pumping the stomach (gastric lavage), which will help to reduce the likelihood of irreversible harm.

After vomiting, activated charcoal may be administered to help absorb some of the aspirin that remains.

Your cat’s condition may require the use of fluids and other supportive therapies. Until your cat is stable, hospitalization and repeated blood tests will usually be required.

Prescription pet medications to encourage healing, or to protect the gastrointestinal lining, are also generally prescribed both in the clinic and for a period of time after returning home.

Aspirin for cats has several clinical uses. It can be prescribed as an anti-inflammatory, anti-pain, and anti-blood-clotting medication. It can also be applied to lower elevated body temperatures.

It is imperative that you strictly adhere to your veterinarian’s instructions, regardless of the reason behind your cat’s aspirin prescription. This also applies to the kind of tablet, as some coatings may make your cat more susceptible to toxicity.

If your pet is exhibiting signs of toxicity, you may need to lower or stop their aspirin dosage.

No NSAID has been approved for long-term use in cats. Meloxicam and robenacoxib (Onsior) are the only two FDA-approved NSAIDs for cats that can be used for a brief period of time, according to PetMD. Both require a prescription from your veterinarian and are only meant to be used temporarily. Your veterinarian must prescribe the appropriate dosage of meloxicam for cats; DO NOT use human prescriptions for cats.

NSAIDs made specifically for dogs, like the well-known chewable carprofen tablet (Rimadyl), are frequently used to treat arthritis or pain following surgery. These are available with a prescription from your veterinarian or even from a reliable internet pet store. Your veterinarian may provide you with other NSAIDS, particularly for pain in dogs. Some NSAIDs are also injectable.

If your veterinarian does advise aspirin, they alone should calculate the appropriate dosage based on your dog’s weight. Dogs now have access to specific formulations, some of which come in the form of oral gel. Moreover, combining aspirin with other animal NSAIDs, like Derramax, Metacam, or Rimadyl, can result in adverse effects like bleeding and stomach ulcers.

Aspirin is a non-steroidal antiinflammatory drug (NSAID). It has been used by people for more than a century to block an enzyme linked to pain and inflammation. Newer, safer NSAIDs designed especially for arthritis-prone dogs may be preferred; avoid giving dogs human NSAIDs like Advil, Motrin, or Aleve as they are toxic.


How much aspirin do you give a cat?

But cats have different metabolisms to humans, and can break aspirin down only very slowly. So while you can give aspirin to a human at doses of 10mg/kg of body weight every 6 hours, with a cat, you can give the same dose (10 mg/kg) – but every 48 hours, not 6 hours. That’s the timing for anti-platelet activity.

What pain reliever can you give a cat?

Only two NSAIDs are FDA-approved for cats: meloxicam (sold under several brand and generic names) and robenacoxib (sold under the brand name ONSIOR). Meloxicam is approved for cats as a one-time-only injection to control pain and inflammation after spaying, neutering, and orthopedic surgery.

Will aspirin hurt a cat?

It is important to dose your cat carefully, as cats are very sensitive to aspirin. Because aspirin clears more slowly from a cat’s system, if dosed incorrectly, it can build up in your cat’s system and cause toxic effects. Kidney and liver damage can occur. Follow your veterinarian’s instructions carefully.

What can I give my cat for tooth pain?

NSAIDS are usually the first line of defense. The FDA hasn’t approved any NSAIDs for long-term pain management, but certain ones are cleared for short-term use in cats. Your vet may prescribe the pill robenacoxib, which is also available as an injection.
