Ardilla Gris Oriental

Native to eastern North America but successfully introduced to Europe and other regions, the eastern gray squirrel is a medium-sized arboreal rodent weighing up to 600 g. Highly adaptable, thriving in forests, parks, and urban gardens, gray squirrels cache thousands of nuts and seeds each autumn, inadvertently planting trees through forgotten caches. In Britain, they have largely displaced the native red squirrel by outcompeting them for food.

house mouse

Among the most widespread and numerous mammals on Earth, house mice originated in South Asia and have accompanied human civilization across every continent except Antarctica. Weighing just 15–25 g, they are highly adaptable omnivores capable of surviving on minimal food and water. As the world's most commonly used laboratory animal, the house mouse has contributed to virtually every branch of biomedical research. They cause significant agricultural damage globally.
