Ah, ok then! I just cut some of mine off(Devils Ivy) and hung it in the waterfall in the pond. Going straight from in the house this time to full sun might not do so well. Last time I did it I put it out on cloudy days and it gradually went full sun. We shall see.
I just looked up Arrowhead and it says it's poison too and uh oh I looked up Pothos and it is too! Guess I'll be going out now and pulling that outta the pond. Hmmmmmmmmm, maybe not tho as I had it in there before and had tons hanging w/ the roots in the aquarium and no fish bothered by it. Maybe fish are not affected as dogs and cats are?
