Next, assemble the cage according to the instructions that come with it. If you have any questions about assembly, feel free to contact Zilla customer service for assistance.

How to Set Up Zilla Critter Cage

Once the cage is assembled, it’s time to add bedding. Choose a soft, absorbent material like Carefresh or Yesterday’s News. Avoid using cedar or pine shavings, as these can be harmful to small animals.

Be sure to place the food dish on the side of the cage that has the bar spacing that is appropriate for your pet’s size.
