I love those, but if anyone eats them, I was told they're poisonous.
That is a big part of my issue: One list says its fine, another implies looking at it will kill your bird.
Yeah, Snake Plant appears to be a consistent "no" for cats and dogs, but it's a mixed message for birds (isn't everything?).
Snake plant contains
Saponin...
In plants, saponins may serve as anti-feedants, and to protect the plant against microbes and fungi.[citation needed] Some plant saponins (e.g. from oat and spinach) may enhance nutrient absorption and aid in animal digestion. However, saponins are often bitter to taste, and so can reduce plant palatability (e.g., in livestock feeds), or even imbue them with life-threatening animal toxicity. Some saponins are toxic to cold-blooded organisms and insects at particular concentrations. Further research is needed to define the roles of these natural products in their host organisms, which have been described as "poorly understood" to date.
Well, since the jury's out, they're not the easiest to land on, my guys have left them alone for years, and I haven't managed to kill them in the same span... they're staying.
