The dried herbs are made by a few companies and I recently purchased two bags for variety. Burgess Supa Excel Country Garden Herbs 120g bag £1.90p and Naturals Herbal Garden 100g £2.69p. Both from Pet Supermarket online. They do free postage on all orders if you choose that option at checkout. I`ve ordered twice from them on a Sunday and both times, my orders arrived on the Thursday evening by courier.
Although Pets At Home and smaller independent pet shops should stock the Burgess ranges and possibly the Naturals ranges aswell.
Feeding-wise, I just give a small `pinch` of the herbs inside the cage every couple of days so they get nibbled up! I find adding too much gets wasted. My little roborovski goes mad for the fresh scent they have, like a cut lawn or a newly cut meadow. They smell really lovely and the sell by date on both my bags is well into 2014!
I went to bed last night and heard my robo nibbling on one of the twigs!
The herbs look just like dried grass with leaves and nettles dried in. There is also mint and chamomile in there. Great fibre source and very natural.
