I love candles too, and some smell so good, I am tempted to take a bite too! LOL. I do have to keep mine up and out of the way - but mostly because I am just so clumsy, I would be sure to knock them over.
Candles seem to be a favorite for some bunnies. I don't know if it's the scent and soft texture that make it irresistible, but I know that candles are on the "caution list" of things to watch for during Christmas. I haven't read where it's toxic, though I can't imagine large amounts are good! But caution was geared more to the fact that some bunnies like them so much that they may try to get them even while they are burning.
