Accepted scientific name and distribution data for Oncidium sphacelatum.
No, the Golden Shower Orchid (Oncidium sphacelatum) is considered non-toxic to cats. It is classified as generally safe, meaning it is not expected to cause poisoning even if your cat chews on or eats part of the plant.
No symptoms are expected from a small nibble. If your cat consumes a large amount of the plant's fibrous material, it may experience mild vomiting or gastrointestinal upset due to the bulk of plant matter, not any toxic compound.
A small amount is unlikely to need veterinary attention. If your cat ate a significant portion of the plant and is showing signs of distress — persistent vomiting, lethargy, or refusal to eat — contact your veterinarian.
Non-toxic means the Golden Shower Orchid won't poison your cat, but that doesn't make it safe to eat in quantity. Large ingestions of any fibrous plant material can cause GI upset, and it's best to keep the plant out of reach to avoid your cat developing a chewing habit.
No, the Golden Shower Orchid (Oncidium sphacelatum) is considered non-toxic to dogs. It is classified as generally safe, meaning exposure is not expected to cause poisoning.
Symptoms are not expected from small amounts. If your dog eats a large quantity of the fibrous plant material, mild vomiting or gastrointestinal upset is possible due to the physical bulk rather than any toxic compound.
A nibble is unlikely to cause any problem. If your dog ate a significant portion of the plant and is showing signs of distress such as repeated vomiting or lethargy, contact your veterinarian.
No — these are unrelated plants. The Golden Shower Orchid (Oncidium sphacelatum) is a safe, non-toxic orchid; the name 'Golden Shower tree' refers to Cassia fistula, a different plant entirely.
