Colours Code:
SLIGHTLY TOXIC PLANTS: in these plants there are irritant substances, but many cats show no symptoms of poisoning. POISONOUS PLANTS: may induce drooling, vomit, diarrhea, cramps. Juice may produce painful mouth swelling, rash or dermatitis. DEADLY PLANTS: if ingested, cause serious effects to major body organs (liver, heart or kidney). Most of them can be fatal.
