Practical information about the nutritional needs of cats and dogs at each life stage, including growth, maintenance, reproduction and aging.
Kitten & Puppy
Neutering may increase a pet’s risk for becoming overweight. The age when a dog or cat is neutered often corresponds with a natural decrease in the pet’s growth rate and energy needs. Neutered animals also tend to consume more food and have a reduced basal metabolic rate — meaning they require less energy to keep the body functioning at rest.
"Now that your [dog/cat] has been neutered, you should feed [him/her] a little less. Neutered pets tend to need less energy, but want to eat more, so cutting down on their food intake helps to ensure that they stay lean and healthy."
