Cat poisoning can cause vomiting or diarrhea, but signs may also affect breathing, balance, bleeding, urination, or behavior. If you suspect your cat has swallowed, inhaled, or otherwise encountered a toxic substance, contact a veterinarian or emergency clinic promptly—even if your cat seems fine. Do not wait for symptoms to appear.

What signs can poisoning cause in cats?

Signs vary with the substance and the amount of exposure. A cat may show one sign, several, or none at first; symptoms alone cannot confirm poisoning, and similar problems can have other causes.

Digestive and appetite changes

  • Sudden or repeated vomiting
  • Diarrhea
  • Loss of appetite

Neurologic or behavior changes

  • Unusual sluggishness or lethargy
  • An unsteady gait or poor coordination
  • Drooling
  • Seizures
  • Not responding normally

Breathing, bleeding, or urinary signs

  • Difficulty or heavy breathing
  • Blood in the stool or urine
  • Bruising or nosebleeds
  • Inability to urinate
  • An irregular heartbeat

Household and environmental hazards include human medicines such as ibuprofen, dog flea products, rodenticides, household cleaners, antifreeze, and lead-containing materials in older homes. This is not a complete list, and a substance’s danger cannot be judged by whether symptoms have started.

What should you do if you suspect exposure?

  1. Move your cat away from the source. Prevent further contact without putting yourself at risk.
  2. Call a veterinarian or local emergency veterinary clinic promptly. Tell them what happened and follow their instructions. Do not wait for symptoms to develop or worsen.
  3. Gather exposure details and evidence. Keep the container, label, remaining pills, or a clear photo of the substance. Be ready to describe what your cat may have encountered, how much, when, and your cat’s age, weight, health, and current signs.
  4. Follow professional guidance about transport and care. A veterinarian or poison-control professional can assess the case and advise on the appropriate plan.

In the United States, ASPCA Poison Control can be reached at (888) 426-4435. Its service is available 24 hours a day, 365 days a year; a consultation fee may apply. Poison-control staff use the exposure details and the animal’s condition to recommend next steps, which may include home care or veterinary treatment.

When is poisoning an immediate veterinary emergency?

Go to the nearest veterinary hospital immediately if your cat is having seizures, struggling to breathe, bleeding, not responding, or unconscious. If possible, have someone call the hospital while you travel. Bring the product container, label, or a photo of the substance if available.

What should you avoid doing at home?

Do not induce vomiting or give milk, charcoal, medication, or another home remedy unless a veterinary professional specifically directs you to. Vomiting can cause additional harm with some substances. Cornell Feline Health Center’s guidance is explicit: “DO NOT induce vomiting unless you are specifically directed to do so.”
