Plant identity
Governed scientific identity: Cissus discolor
Also called: Rex Begonia Vine
Climbing Begonia is Cissus discolor, not a Begonia. ASPCA prints Cissus dicolor; that source spelling is retained as evidence metadata, while the governed public identity is Cissus discolor. Rex Begonia Vine is a scoped search alias only.
What non-toxic means
The ASPCA-listed identity is non-toxic; ingestion can still cause nonspecific gastrointestinal upset.
If your pet chewed it
Remove access after chewing and monitor your pet. Contact a veterinarian for concerning or persistent symptoms.
Prevention and placement
Guide trailing stems away from pet access and promptly remove chewed or fallen leaves.
Evidence scope
Do not apply this Cissus discolor conclusion to Begonia, Rex Begonia, Begonia maculata, Cissus javana, or any other Begonia/Cissus identity without separately governed evidence.
