Sharron, you're right. Knowledge is power. Right now, none of the plants I have are toxic. I am a stickler for that type of thing, because if it's not my animals getting sick, it could be someone elses, and I would never forgive myself.
As for a b nipping off rose shoots, well… that would just mean that the rose would have no flowers! It might not look like it, but the yard/garden is maintained for the enjoyment of all of us - humans and pets. I love my garden, but I love my animals first.
