Amphetamine Toxicity in Cats

A prescription medication, amphetamines are used to treat ADD/ADHD and narcolepsy in humans. They are used for weight loss as well. They can also be obtained illicitly (crystal meth, methamphetamine, ecstacy). When ingested by your cat, however, amphetamines can be very toxic.

Amphetamine toxicity can occur in both dogs and cats. If you would like to learn more about how it affects dogs, please visit this page in the petMD health library.


Possible symptoms of amphetamine poisoning in cats include:

  • Restlessness
  • Panting
  • Hyperactivity
  • Sedation
  • Agitation/irritability/aggression
  • Muscle tremors
  • Seizures
  • Increased heart rate
  • Dilated pupils
  • Elevated blood pressure
  • Vomiting
  • Diarrhea
  • Drooling
  • Death


Most cases of amphetamine poisoning in cats are accidental, caused by the cat ingesting pills that are dropped on the floor. Cats may also find and ingest medication from pill bottles left on countertops and in other accessible areas. Occasionally, the drug may be given to the cat purposely.


After asking you questions regarding the cat's medical history, your veterinarian will observe the animal for clinical signs consistent with amphetamine ingestion. Blood, urine or stomach contents can be tested for the presence of amphetamines, but it generally takes several days for results to be obtained. Therefore, treatment for amphetamine poisoning must be initiated before these results are returned.
