  • Obesity in cats is associated with an increased risk of a shortened life span and several health conditions, including osteoarthritis, diabetes mellitus, urinary tract diseases, liver problems, lameness and skin diseases.
    • A recent study also reported a high body condition score to be associated with hypertension, asthma, diarrhea, eye problems and allergic conditions in cats.
  • Routinely monitoring a cat’s body condition at home is simple and easy ꟷ look for a waist from above, check for a tummy tuck from the side and feel over the ribs. 
    • If changes are noticed in a cat’s body condition, the amount of food fed can be adjusted as needed.
