What to do
Contact a vet, especially for seed ingestion, since seeds carry the highest concentration of the hallucinogenic alkaloids.
Toxic component and mechanism
The toxic component in Morning Glory is ergot-like alkaloids (lsa), concentrated in the seeds.
Part-specific risk: Seeds are far more concentrated in toxins than leaves or flowers.
What makes this plant different
Morning Glory seeds contain LSA, a compound structurally related to LSD, and are occasionally sought out intentionally by humans for their psychoactive effects — this is worth knowing if a pet has access to a garden where seeds have been deliberately collected or stored, not just growing on the vine.
