I have 6 cats ranging from 4months to 3years , they are all the right weight for their age etc .
My problem is why the hell are they always so hungry , they get fed properly yet they are always begging for more or rooting in bins I can't even leave any food on the side for a second else they will take it & when they eat it's as though they have never been fed before 
I wormed them two weeks ago so it can't be worms , can it ?
They all get Two pouches a day & constant access to fresh biscuits .
I'm at my wits end with them to be honest & I just don't know what to do
