Every time I open the cage door Myka Degu takes a bite sized chunk out of the edge of the MDF. It's a little bit of an oversight on my part as I didn't think It would need protecting as they can only get at the edge when the door is open. I've left repairing it for as long as possible but the tools had to come out today as it's too bad to ignore any longer. I actually watched her pull a piece off with the door shut!
Life as a degu owner and the life of a degu.
