WHRS Class 2: local or weaker toxin · Wisconsin House Rabbit Society chapter list (G. Flentke, 2012): Class 2 — "Local toxins": "Allergens, dermal sensitivity toxins, or systemic toxins of lesser strengths" (list heading: "May cause allergic reaction in rabbits. Be cautious."). WHRS adds that, because rabbits inevitably chew items, these toxins "could be more of a problem than the current literature indicates".

peer-reviewed
Peer-reviewed experiment (PMID 1577644) · fresh plant material (powdered) · Pairs of budgerigars were given powdered fresh plant material by gavage; of 19 plants tested only 6 induced clinical signs of illness. The abstract does not name the other 13 plants, so it supports no safe/non-toxic claim for any plant. The abstract says Clematis sp (species not named); the ASPCA entry is also genus-level (Clematis spp.).
Of the 19 plants tested, only 6 induced clinical signs of illness; these plants included yew, oleander, clematis, avocado, black locust, and Virginia creeper (Taxus media, Nerium oleander, Clematis sp, Persea americana, Robinia pseudoacacia, Parthenocissus quinquefolio).
