Ken, thank you for the links!
I have to find fault with Maurice's logic regarding his caution that a plant with toxic components in its roots may likely have those toxins in its other parts. While it *could* be true, it isn't a fair assumption. Consider tomatoes, for instance. All parts of the tomato are toxic except the tomato itself. That doesn't mean that the daylily bud isn't toxic, just that the logic doesn't completely hold up.
I do find fault with the notion of extrapolating that something toxic to cats is toxic to humans, but I do need to read the thread more before I can offer much more comment to that statement; though I will say that even a quick glance at ASPCA's toxic plants lists will show there are many things that harm cats (or dogs) that don't harm us.
