Oh well, will keep looking for bramble bushes or hawthorn near me!
Thanks all, I misread the post.
My friend normally supplies me with bramble leaves as I have none nearby, but she's now left my work so will replace them with hawthorn since they're good for digestion too. Will cut a few branches off for Doughnut and take the flowers off.
Thanks will get my gloves at the ready! Why is it most things for bunnies hurt us, bramble leaves, hawthorn, nettles!
