Autumn crocus blooms in the fall and when ingested may cause vomiting and diarrhea. It is highly toxic and can cause kidney and liver damage as well as gastrointestinal bleeding. Signs of toxicity may be immediate or can be delayed for days.
Eating just a few leaves of azaleas can cause excessive drooling, vomiting and diarrhea. Coma may result and can be fatal. Easter lilies are also highly toxic to cats. Ingestion may result in kidney failure. A cat that has been exposed to any part of an Easter lily plant should be seen by a veterinarian as soon as possible to be treated for poisoning. Morning glories are highly poisonous to cats. Ingestion can cause agitation, disorientation, hallucinations and tremors.
