I am sure the ASPCA has been advised of this fact. My thought is most people don't know the difference and better to err on the safe side and include daylilies in the toxic plant list. Hostas are related to daylilies as well. I know for a fact one of my cats has chewed on seedlings I had growing in the house with no adverse affect. I do however shoo her away. You can send me picture. I will see what I can do. We ID plants at work all the time for people.
