Im obsessive as you,Nails are done every Monday food bowls and water dishes are washed everyday after being used,The water buckets are brought in every night and washed im also a clean freak.so maybe that is why im like that in my house,garden nothing is ever out of place it will drive me crazy!There is nothing wrong with the way you do things your just a responsible pet owner,and take there needs i know i would not eat off a dirty plate neither should they!
