After doing a lot of research and joining forums etc, I've just ordered 3 and a half kilos of raw minced wild and farmed whole rabbit. Yikes! This is from a specialist supplier in the UK who only deals in rabbit, for pets and for humans.
I may also order some poultry necks and hearts, from the UK Barf club. But I'll see how I go on with the rabbit first. Last night I gave the lads raw liver with some chicken in gravy from a pouch, with some raw egg and ground eggshell mixed in. They loved it! So I am encouraged.
I also like the idea of buying some frozen mice to throw into the garden, so that they can pretend they've caught their own dinner...but ordering from reptile food suppliers is quite expensive (200 mice minimum order!) so that idea is on the back burner.....or do I not really have the stomach for that?? LOL!
