Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.

What this means for your cat

Cats rarely eat Nightshade in quantity, and the cited sources note that toxicity is uncommon unless a substantial amount of leaves, stems, or unripe berries is ingested. When poisoning does occur, expect both gastrointestinal and neurologic signs.

What to watch for

Most common: drooling, vomiting, diarrhea, loss of appetite, and drowsiness. Less common but serious: dilated pupils, slow heart rate, confusion, weakness, or unusual behavior.

Time window

Exact onset is not well documented in the cited sources; gastrointestinal signs typically appear within hours of ingestion.

When to call the vet

Call your vet or Pet Poison Helpline (855-764-7661) the same day for persistent vomiting or diarrhea, and immediately if you see dilated pupils, tremors, slowed heart rate, or any change in behavior.
