Can Cats Eat Mulberry Leaves? Vet-Reviewed Safety Guide

As a veterinarian, I often get asked about which plants are safe for cats. Mulberry trees are common in many yards, but their leaves pose a risk to our feline friends. Let’s break down why mulberry leaves should be kept away from cats.

Is It Safe or Toxic and Why?

Mulberry leaves are not safe for cats. They contain tannins and cyanogenic glycosides, which can break down into cyanide when ingested. This can lead to symptoms ranging from mild gastrointestinal upset to severe poisoning, including difficulty breathing and seizures.

Health Benefits or Risks

There are no health benefits to feeding mulberry leaves to cats. The risks include vomiting, diarrhea, lethargy, and in severe cases, respiratory distress or even death. Even small amounts can cause problems, so it’s best to avoid them entirely.

Safe Serving Size and Preparation if Applicable

There is no safe serving size for mulberry leaves in cats. They should never be offered, cooked or raw. The toxins are present in the leaves regardless of preparation.

Symptoms of Trouble

If your cat eats mulberry leaves, watch for drooling, vomiting, diarrhea, weakness, difficulty breathing, dilated pupils, or seizures. These symptoms can appear within hours of ingestion.

What to Do if Your Cat Ate Too Much

If you suspect your cat has eaten mulberry leaves, contact your veterinarian or the ASPCA Animal Poison Control Center at 888-426-4435 immediately. Do not induce vomiting unless directed by a professional. Bring a sample of the plant if possible.

Safety note: Keep cats away from mulberry trees entirely, especially the leaves and unripe fruit, and seek veterinary help immediately if ingestion is suspected.
