My indoor-outdoor cat has been nibbling a few fertilizer pellets from my potted plants every day for a week — what's the long-term risk?

Short answer

This is an urgent situation requiring immediate action. Repeated daily exposure to fertilizer, even in small amounts, allows toxins like iron, organophosphates, or blood meal to accumulate, leading to chronic poisoning or organ damage. Signs can include vomiting, diarrhea, lethargy, and in severe cases, seizures or organ failure. Call the ASPCA Animal Poison Control Center at 888-426-4435 or your vet right away, and bring the product bag with you. Prevent further access and wash any residue from your cat's paws and fur.

Why is this dangerous?

Blood meal and bone meal smell like food, so dogs eat them readily — and a large amount of blood meal can cause pancreatitis and severe gut upset.

Organophosphate and carbamate insecticides in combined “weed and feed” products block an enzyme that controls nerve signals, causing SLUD signs — salivation, lacrimation, urination, diarrhoea — and muscle twitching. Iron-containing fertilisers add iron poisoning.

Why speed matters

Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.

Signs to watch for

  • Drooling, watery eyes, vomiting, diarrhoea
  • Pinpoint pupils, muscle twitching, tremors
  • Weakness, difficulty breathing, slow heart rate
  • Abdominal pain, restlessness, pacing
  • Bloody vomit or dark stools if iron-containing

What to do right now

  1. Call your vet or a poison line and read the product label — the active ingredient changes the treatment.
  2. Bring the bag; wash pellets off the fur and paws so grooming does not continue the exposure.
  3. Do not induce vomiting unless instructed.
  4. Store fertiliser in a sealed container, and keep pets off treated lawns until watering has soaked it in.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
