My cats like the grassy texture of Dracaena marginata, and D braunii must be tempting also. Dracaena, as the whole genus, is listed toxic by APSCA. I know my cat(s) chewed on my two plants quite a bit yet I never saw the effects listed. (Cats, vomiting, that's pretty common anyway)

Oxalis is tasty.
this site has a really good article but I don't find complete information about toxic plants there, just this one

think part of the problem with lists that have been made is that the word toxic doesn't allow for shades of grey. So anyone referring to lists then is faced with vetting that information. Ultimately, if you really want the best info, on anything, you have to check multiple sources.
Just today, I read that all parts of sweet potato plants are edible EXCEPT the seeds, which contain something similar to LSD. So, as an author of a list, do I include this plant or not?
This site, too, like ASPCA, does in some cases try to indicate mild-severe and tell you what kind of toxin is involved.

Geoff Stein has at least one article on pets and toxic plants, that ran at Daves Garden years ago. He's a veterinarian AND a plant nut, so that seems an excellent combination for knowing what's really up. Too bad he doesn't talk about many common houseplants (NOTE: Florist Kalanchoe , and Azalea, and Easter lily, common gift plants at some times during the year, do rate very toxic to him for those animals that will chew on them. ) But he does explain some thought process and from a vet's persepctive and experience.
