Norwegian rats are one of the most commonly used feeder animals for snakes, monitors, and other reptile predators. As whole prey feeders, they provide muscle tissue, bone, organs, and fat, which together support natural nutrition and healthy growth.
At Caliber Exotic Supply, our feeder rats are responsibly bred and raised to produce healthy feeder animals suitable for reptiles of different sizes. Each feeder is graded by size so reptile keepers can choose prey appropriate for their animal.
Feeding Guidance
Selecting the correct feeder size is important for safe feeding.
Two commonly used guidelines are:
• Width Rule – Choose prey roughly the same width as the widest part of the reptile’s body.
• Body Weight Rule – Many keepers feed prey that is approximately 10% of the reptile’s body weight for maintenance, or up to 15% of body weight when encouraging healthy weight gain.
Every animal is different, so feeding schedules and prey size may vary depending on species, age, metabolism, and overall body condition.
Whole Prey Nutrition
Whole prey feeders naturally contain:
• muscle protein
• calcium from bone
• essential fats
• organ nutrients
Because of this natural balance, rats are considered one of the most nutritionally complete feeder options for carnivorous reptiles.
