Animals and birches
Since birch extracts have a strong dehydrating effect, caution is advised with some animals. Although there can be no question of a poisonous effect here either, some pets feel less well after nibbling on birch leaves or the bark. These include, in particular, budgies. Basically, there is nothing to be said against consumption in moderation in the case of birds or horses, for example.
