Abstract:

Plant poisoning is a frequent cause of intoxication in companion animals. This case reports hepatopathy in a cat temporally associated with suspected ingestion of Philodendron spp., a plant species known to cause gastrointestinal irritation. A 6-year-old spayed female European Shorthair cat developed anorexia, lethargy, and jaundice after the suspected ingestion of Philodendron spp. leaves. Diagnostics testing showed increased liver enzyme activities and hyperbilirubinemia, consistent with acute hepatic injury. Supportive gastrointestinal and hepatic management was instituted, and full recovery was achieved after 55 days. This case highlights the potential for atypical presentations following plant exposure. Although Philodendron toxicity is classically attributed to calcium oxalate crystals, hepatopathy in this cat may reflect the involvement of other phytotoxins and/or secondary hepatic lipidosis triggered by anorexia. Nonetheless, the underlying cause remains unclear. Since documented plant poisonings in companion animals are scarce, case reporting is essential to advance veterinary toxicology.
