            et al. 2011) and 15 to 25% for dogs (Laflamme 1997b;   (Kealy et al. 2002), which corresponds better to the
            Kealy et al. 2002)                                optimal BCS found by Mawby et al. 2004. The ideal BCS

              Cats Studies have shown that neutered cats are at
            risk of accumulating more fat than intact cats (Fettman   The main objective of most studies validating the BCS
