That's actually a good idea for people with animals that share their living space who foster psychoactive plants as well.
I don't know if any research on animal toxicity in and of itself, but most, if not all human research is preceded animal testing. Rick Doblin often bemoans this fact as a unfortunate necessity. However, beyond simple lethality, i doubt there's much useful information in published papers.
Sorry i couldn't be of any help with info, i just want to support the idea of compiling a companion animal/plant safety database
