I found some dried twigs of crepe myrtle and thought about giving it for my bunnies to chew on, is it toxic to them? Is there a list somewhere that has what woods are toxic to rabbits?
The House Rabbit Society has a list of toxic plants - http://adoptarabbit.org/articles/toxic.html
- and Myrtle's not on it.
You said that the twigs were dried - that's good. A general rule is that nearly all woods (except apple) need to be dried for a month or so before you let rabbits chew on them.
