Dangerous (Poisen) plants for cats

House & garden bunches, trees, herbs, flowers and other ornamental plants always look great (if you have cats you need to be careful about which ones you chose). If your cats are indoors/outdoors, you have to be careful about the plants that you grow indoors/outdoors.

Symptoms of poisoning (if you suspect poisoning, call you vet!!!):

  • diarrhea
  • convulsions
  • if tongue and gums are pale or swollen
  • fainting
  • listless
  • refusing food and water
  • vomiting
