A well-equipped ferret cage should include a variety of elements to ensure both comfort and stimulation. Secure, cozy bedding and a hammock are essential for rest, while sturdy chew toys and tunnels provide necessary entertainment and exercise. Additionally, a litter box is crucial for hygiene. It's important to choose safe materials and structures specifically designed for ferrets to prevent any accidental ingestion or injury. Regular updates and checks of the habitat's accessories are advisable to maintain a safe and engaging environment for these active pets.
