Today was the weekly cage cleaning day. Mercedes has been doing very well lately being able to bond more and is very chirpy. I started to take out his ladder and noticed a chunk line was gone. This was the ladder he normally slept on and I always saw him rub his head on it. I never thought of anything of the fact he could even begin to chew on the ladder like that. I checked his poop and its completely normal so I don't think he ingested the ladder. I was just wondering if that's normal behavior and if I need to remove the ladders. I do have a mineral block in the cage which he hasn't even touched. He also has his food replaced 2 times a day so he shouldn't ever be hungry.
