Kalanchoe
These brightly flowered succulents make lovely gifts to bring a bit of color to someone’s holiday. However, they are mildly toxic to both cats and dogs, causing vomiting or diarrhea in both animals. It’s been reported that in rare cases, abnormal heart rhythm can develop.
Symptoms are generally mild, but if you have a pet and a kalanchoe, you will want to put the plant where Fido or Frisky can’t reach it.
