Can anybody tell me if daffodils are dangerous to cats and how high this danger is? Fatal case or not? I have daffodils in my garden and my cat walks in there often. So far so good but when a friend of mine came over and saw it he was in panic saying I should protect my cat from daffodils.
Daffodils are indeed very toxic to cats. I couldn't tell you for sure the percentage but I do know there are specific plants that can cause seizures, vomiting, blood pressure to drop and even death. http://www.aspca.org/Pet-care/poison-control/Plants/daffodil.aspx
Aren't cats smart enough to never chew on poisonous plants like daffodils?
Not necessarily. I've seen it happen, it's not worth the risk.
