The Sprengeri Fern, also known as Asparagus densiflorus, is a popular ornamental plant that is toxic to cats. While cats are not technically allergic to this plant, ingesting any part of it can cause serious health issues.

Potential diagnosis your Vet may give

Your vet will likely diagnose Sprengeri Fern toxicity based on:

  1. A history of your cat having access to the plant
  2. Presenting symptoms
  3. Ruling out other potential causes

Your vet may recommend induced vomiting if ingestion was recent or activated charcoal to absorb toxins. Intravenous fluids and anti-nausea medication may be given to prevent dehydration and make your cat more comfortable. Most cats recover fully with prompt supportive treatment.
