After being spayed or neutered, our pet’s metabolism slows down, but their appetite actually increases. This means they needs fewer calories than they did before the procedure, but they feel like they need more. That is why it’s so important to feed a diet designed for spayed and neutered dogs and cats. VETERINARY HPM® Pet Foods supports appetite control, helping the pet to feel full while avoiding excess calories. This diet has feeding guidelines for weight loss, management, and maintenance.
