Nutritional deficiencies are worse.

    A nutritional deficiency causes two problems:
  • requires your pet to eat more just to obtain the nutrient it needs – causing other nutrients to be in ‘excess’
  • eating more causes ‘un-used’ nutrients to be ‘stored’ (calories are stored as more body fat) or ‘eliminated’ (wasted protein/amino acids stresses the liver and kidneys – unbalanced minerals stresses many organs within the body).
