Toxic Plants


  1. It is suggested by several sources Readers Digest and various Medical Journals that the number of poisoned animals may be only 1 to 2 percent of the total number of cases that are seen by vets each Year.
  2. They also suggest that there is no difference between the sexes. Meaning both are affected equally.
  3. There is also no specific season for variation in poisoning's, but specific agents do have seasonal peaks. These include exposure to insects stings (like bee's and wasp), snake bites, ethylene gycol (automotive antifreeze which they lick off of the skin), and pesticides and rodenticide compounds.
  4. Cat's are generally less frequently poisoned than dogs.

Size and breed do not make a difference!!!
