What Are the Dangers of String of Turtles for Cats?

String of Turtles can be dangerous for cats when ingested because this plant is a semi-succulent that contains calcium oxalate crystals and saponins, both of which are dangerous for cats. Due to these components, ingesting a String of Turtles could potentially be harmful to your cat and lead to several health problems, mainly related to the gastrointestinal (GI) tract.

Symptoms of String of Turtles Consumption:
  • Vomiting
  • Abdominal pain
  • Lethargy
  • Excessive drooling
  • Lack of appetite
  • Diarrhea

It’s also possible for cats to experience an array of health issues due to the oxalate crystals inside this plant. Chewing or biting into these crystals can lead to your feline experiencing mouth irritation, swelling, and GI problems. Cats may also experience difficulties breathing, oral pain, pawing at the mouth, and an appetite decrease.
