Sweet peas contain lathyrogens, a type of toxic amino acid that can cause:

🚨 Neurological problems
🚨 Muscle weakness

Even a small amount can lead to vomiting, diarrhea, or lethargy, while large amounts can cause serious nerve damage over time.

Tip: If you have indoor or outdoor cats, it’s best to avoid planting sweet peas in areas they can access.

If your cat eats sweet peas, watch for the following symptoms:

⚠️ Vomiting

⚠️ Tremors or seizures (in severe cases)
⚠️ Loss of appetite
⚠️ Difficulty walking or uncoordinated movements

How Long After Eating Sweet Peas Will Symptoms Appear?

Symptoms can appear within a few hours of ingestion and may last for several days depending on the amount consumed.

Important: If you notice any of these symptoms, contact your vet immediately for advice.

3. What to Do If Your Cat Eats Sweet Peas

🚨 Step 1: Remove your cat from the plant to prevent further ingestion.
🚨 Step 2: Check your cat’s mouth for any remaining plant material and remove it gently.
🚨 Step 3: Monitor your cat’s behavior for any signs of poisoning.
🚨 Step 4: Call your veterinarian if you notice symptoms like vomiting, diarrhea, or lethargy.

… are safe for cats in small amounts if fully cooked (but not necessary for their diet).
