How urgent is this?

Emergency

Go to the ER now

  • Your cat ate a marijuana edible, vape cartridge contents, concentrate, or unknown cannabis product
  • Seizures, collapse, coma, severe weakness, or trouble breathing
  • Repeated vomiting, very low body temperature, or inability to stand
  • Your cat may also have eaten chocolate, raisins, or xylitol along with the cannabis product
Urgent

See a vet within 24 hours

  • Your cat ate dried flower, leaves, stems, or ash from marijuana
  • Dilated pupils, wobbliness, unusual agitation, profound sleepiness, drooling, or dribbling urine
  • Possible inhalation exposure plus any abnormal behavior
  • You are not sure what form or how much was exposed
Monitor

Watch at home, call if it worsens

  • Your cat briefly sniffed marijuana but definitely did not ingest it and is acting completely normal
  • Possible secondhand smoke exposure only with no symptoms, but you should still call your vet for guidance because cats can be more sensitive to inhaled irritants

Why Weed Is Dangerous for Cats

There is no safe serving size for cats. THC affects the brain and nervous system and can cause depression, incoordination, vomiting, abnormal excitement, low blood pressure, low body temperature, seizures, and, rarely, coma or death. Cats may also be exposed through edibles, oils, or smoke, and edible products can be even more dangerous because they often contain additional toxic ingredients. Compared with dogs, cats appear less commonly exposed, but they can show marked neurologic signs and may be more likely to show agitation or excitation instead of just sedation.

  • Do not offer marijuana, THC products, or cannabis edibles to your cat
  • Keep flower, oils, gummies, brownies, and vape products stored securely out of reach
  • Do NOT induce vomiting unless a veterinarian specifically tells you to do so
  • If exposure happened, tell your vet exactly what product was involved and when
  • Call your vet promptly even if signs seem mild, because symptoms can worsen

Common Questions

Can cats safely eat a small amount of weed?
No. There is no known safe serving size of marijuana for cats. Even small amounts of THC can cause toxicity, and edibles may contain other ingredients that are dangerous to cats.
Are cats affected differently than dogs?
Both cats and dogs can be poisoned by THC. Dogs are reported more often because they are more likely to eat cannabis products, especially edibles, but cats can still become seriously ill. Cats may show depression, incoordination, vomiting, dilated pupils, drooling, low body temperature, or sometimes excitation and agitation.
What symptoms can marijuana toxicity cause in cats?
Possible signs include sleepiness, disorientation, wobbliness, vomiting, drooling, dilated pupils, low blood pressure, low body temperature, urinary dribbling, agitation, seizures, coma, and, rarely, death. If your cat has any of these signs after possible exposure, call a veterinarian right away.
Is CBD safe for cats?
Not necessarily. Some CBD products may contain enough THC to cause poisoning, and product labeling can be unreliable. Do not give human cannabis or CBD products to your cat unless your veterinarian specifically recommends a veterinary product.
What should I do if my cat ate weed?
Call your veterinarian or an emergency clinic as soon as possible. If you know the product type, bring the packaging or ingredient list with you. Do not induce vomiting unless a veterinarian directs you to do so.
