Question: is philodendron scandens poisonous to cats?
Answer: A: Philodendron leaves contain calcium oxalate crystals which, if ingested, irritate the gastrointestinal tract from the mouth to the stomach and intestines. Affected cats drool and exhibit signs of abdominal pain. If your kitten chews your philodendron, paws at his mouth and then rubs his eyes, they'll hurt too.
