shell love it, it just turns them on, both of mine cant wait for feeding times and got to each others bowls every night (a couple of times) just to make sure they are empty... to look at me and say come on - gimme some more This is one food that you do not need to over feed on - both mine get measured amounts. Any more than recommended feeding will be wasted - the bag should lasr as long as the 15kg bags of other ranges - around 3 months Mine are on lower to mid feed amounts
