Is philodendron toxic to dogs or cats?
The same oxalate mouth burn as pothos.
Painful but rarely dangerous for cats.
All philodendrons share the calcium oxalate defense: chewing hurts immediately, which limits how much a pet eats. Expect drooling and a sore mouth rather than systemic poisoning. Persistent vomiting or any swelling near the airway is your cue to call.
Signs to watch for
- Mouth irritation
- Drooling
- Vomiting
- Reduced appetite
