hamster chewing ikea knuff

[emma_teddy]

so i just put an ikea knuff (the wooden magazine holder w/ the bottom removed) in teddy's cage as a hide/level. he's tried to chew at some of the edges (i did my best to sand any sharp edges down beforehand). i'm worried it will splinter if he chews on it too much??

i don't have anything to coat it with - i'm not worried about him peeing on it because he's very good with peeing in his corner

if anyone has any advice please respond asap!
