Peach

Yes, peach trees (Prunus persica) are potentially toxic to cats. The leaves, stems, and seeds (pits) contain cyanogenic glycosides, which can cause serious harm. The fruit flesh itself is not the primary concern, but any other part of the plant poses a risk.

Symptoms include vomiting, diarrhea, and lethargy from GI irritation, but the more serious concern is cyanide poisoning — watch for difficulty breathing, panting, brick-red gums, dilated pupils, drooling, weakness, or collapse. Wilted peach leaves are especially dangerous, and cyanide signs can appear within minutes to an hour of ingesting pit material.

Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately — do not wait for symptoms to appear. If your cat shows labored breathing, gum-color changes, weakness, or collapse, go to the nearest emergency vet clinic right away. Mild GI signs from nibbling a leaf may resolve in 24–48 hours with supportive care, but pit ingestion is a same-minute emergency.

The pit (kernel inside the stone) is the most dangerous part because it contains the highest concentration of cyanogenic glycosides. Leaves and stems also contain these compounds, and wilted plant material — such as fallen or cut leaves — is especially hazardous because wilting concentrates the toxic compounds. The ripe fruit flesh is not the primary risk, but the pit, leaves, and stems should all be kept away from cats.

Peach trees are potentially toxic to dogs. The fruit flesh is low-risk, but the leaves, stems, and seeds (pits) contain cyanogenic glycosides that can cause vomiting, diarrhea, abdominal pain, and signs of cyanide poisoning including rapid breathing or shock.

The seeds and foliage are the most dangerous parts. The pit kernel contains the highest concentration of cyanogenic glycosides; wilted leaves are also a significant risk. A whole swallowed pit carries an additional obstruction hazard even if the kernel isn't chewed open.

Cyanide signs can appear within minutes to about an hour after a dog chews open and ingests the pit kernel, with severe cases progressing within hours. GI symptoms like vomiting and diarrhea typically resolve within 24–48 hours, while pit obstruction signs — repeated vomiting and no stool — can build over 24–72 hours.

Call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately if your dog chewed open a pit or ate leaves or wilted plant material. Watch for panting, labored breathing, brick-red gums, dilated pupils, weakness, or collapse — these are same-minute emergencies. A whole swallowed pit warrants a same-day call for obstruction risk even without cyanide signs.
