I don't feed Arden Grange as their main food (I prefer Burns as it is low in magnesium and phosphorus) but I regularly feed the treats (one a day each).  They are marvellous.  They even smell tempting!!!  Maisie and Billy love 'em and if I put them up on the high shelf, Maisie stares longingly up at them, trying to think of a way that she could get to them.  I really recommend these!!!
