I had to laugh out loud when I read, "No cat in its right mind would even nibble on one [poinsettia] (cats are finicky like that)... well, I have a large (16 lb.), young (2-1/2 yrs.) black & white boy cat from Tennessee (named Parker 'cause he was found in a park) and I have always thought his mama had an unholy dalliance with a dog. He chases his tail, "digs to China" in his litter box, plays in the water of his water dishes, chews on wicker, cardboard and anything else he can get his teeth on including a Christmas cactus AND a poinsettia that was given to me recently. I called my vet after I found two of the red bracts chewed off and bite marks on some of the green ones. She told me he might throw up, or at best drool. Did he? Nope! Not nary a dribble! (She told me, however, that all parts of lilies are so toxic that even the pollen is deadly. That scared me; I had lilies in an anniversary arrangement from my husband.) The cactus is outside on a porch (the cat is not allowed outside) but I've had to hide the poinsettia in various rooms; can't even allow him to see it lest he follow me, practically begging for it. I know I need to plant more wheat grass for him. I think I'll buy him a couple of sheets of sod...!
