Ive never had any problems with beefheart. My collection that have been fed it are oscars,red devils,jaguars,dovii,green terrors,convicts and they all have thrived on it.
Mind you though I never buy the crap they sell at the lfs. The stuff I buy is sold for human consumption and I always trim away the slight layer of fat before I process it in the blender with the rest of the ingrediants.
Theresa I will look into editing the page for you once my head clears.. My son Robert has been diagnised with epilepsy and Ive been battling the flu. So its been a shite of a week LOL.
