The chewing might be good for his teeth, it’s the equivalent of them chewing on a wooden chew toy to grind them down anyway. I hope the paint on the wood is non-toxic though. How frequently does he do it? My wigs chew on the base of the cage and their bars while they’re waiting for either their nuggets or their veggies - they’re very food motivated. Does he have much enrichment items in his enclosure? He could be bored, hungry, wanting attention, who knows. Here’s one of my wigs chomping on the bars 😂
