Fun Facts About Rodents

  • Gnawing Machines: Rodents have ever-growing incisors that require constant gnawing to keep them trimmed. This is why they’re often seen chewing on various objects, from wood to metal.
  • Diverse Diets: While some Rodents are herbivores, others are omnivores. For example, rats can consume a variety of foods, while guinea pigs are strictly herbivores, requiring a diet of hay, vegetables and fruits.
  • High Reproduction Rate: Rodents are known for their rapid reproduction. Mice and rats can breed as early as 5-6 weeks old and can produce up to 12 offspring in a single litter. This high reproductive rate contributes to their successful spread across the globe.
  • Superb Memory: Some rodent species, like squirrels, have a remarkable ability to remember the locations of the food they stash. Squirrels can hide thousands of seeds each year and retrieve most of them in the winter months.
  • Social Creatures: Many rodents, such as guinea pigs and hamsters, are social animals. guinea pigs, in particular, are happiest when housed in groups and they will communicate with each other through various vocalizations and body language.
