Using this Kaytee CritterTrail one - level habitat is easy. First, place the food dish and water bottle in the appropriate spots. Fill the food dish with your pet's favorite food and the water bottle with fresh water. Put the exercise wheel in place so your little friend can stay active. When you want to interact with your pet, open the front wire door and use the removable petting zone. To clean the habitat, gently move your pet to the petting zone. It will keep them safe while you clean the main area. As for maintenance, clean the food dish and water bottle regularly to prevent bacteria growth. Check the wire spacing often to make sure it's still secure. Also, when using the CritterTrail Fun - nel accessories to connect it to other habitats, make sure the connection is tight. Always use the habitat in a dry and clean area away from direct sunlight and extreme temperatures.
