This #Caturday is my annual reminder post for holiday plants that might be toxic to your kitties! 馃 
SUPER dangerous, both require immediate calls to poison control and emergency vet visits:
Lilies: the whole plant is toxic: flower, stem, pollen. Even ingesting only a small amount can lead to acute kidney failure.
Yew: also immediately life threatening. There is no safe amount.
Less dangerous, but maybe keep out of where pets can reach them:
Holly: upset stomach, mouth damage from the points on the leaves.
Poinsettias: upset stomach, mostly.
