Hiya Kamie =)
Your cats are not hungry, a low % means they are not hungry. So between 1 and 5 like you said is very good and means they eat correctly!
If it was above 25-30% then this is getting bad and would mean the cats were not eating. A high % is bad, a low % like you have is good ^.^
I hope this will help =)
My cats are always hungry
