Neutered cats often gain weight more easily than non-neutered pets. Hormones in the body cause metabolic changes after neutering, so cats often become much calmer. They still have a good appetite, however, and can put on so much weight that they become obese. These extra kilos are not just a “minor flaw”. Being overweight increases the risk of diabetes, urinary stones and other diseases. The cat’s quality of life and even life expectancy can be much diminished as a result. A high-fibre and satisfying diet with a moderate fat content is recommended to prevent excess weight and its consequences. The ideal food contains lots of protein to stimulate activity and a mineral content formulated specifically to protect the urinary tract.
