Guinea pig toys are essential for keeping these small pets mentally stimulated and physically active. Common types of toys include chew toys, tunnels, and hideouts. Chew toys, made from safe materials like wood or hay, help maintain their dental health, while tunnels provide a fun space for exploration and exercise. Additionally, interactive toys, such as puzzle feeders, encourage foraging behavior, mimicking their natural instincts. Providing a variety of toys can prevent boredom and promote a happy, healthy life for your guinea pig. Always ensure that toys are safe and free from harmful chemicals or sharp edges.
