As a confessing paranoid (not calling you that now
) I was suspicious quite some times when the amount of food was less than my estimated amount - especially when the server was well filled it seemed to flush faster. And after Updates everything seemed a lil queer anyway, food intake as well as breeding behaviour, but ususally all went back to normal after about a week.
I put my cats into the cattery last week and was shocked to see it melting like snow in the sahara, way faster than it should go. But after some suspicious eyeing the food melting rate, I found that it lasted about the time it should have (a few hours amiss, but hey) I thought I was watching when many of the cats were awake and actually eating.
