I just went through this yesterday
.My neighbor was freaking out because they said my Morning Glory vines were poisonous to cats and dogs. Um..only the seeds, not the flowers or foliage and…you’d have to eat a ton of seeds to suffer any toxic effects.
Never seen a cat or dog OD on Morning Glory seeds yet though they do contain Lysergic acid, LSD.
I told them I have grown these vines for years with all kinds of animals and nobody has been poisoned yet. I then emailed them an article from a poison control center discussing plants toxic to pets that specifically states you would have to ingest a large quantity of the seeds to experience toxicity. Maybe I should bake them some Morning Glory seed muffins. Have a nice trip. LOL
