Question about bedding

[Nakuzo]

Hello everyone

I have a bit of a problem/ dilemma with bedding. A little while back, I had bought a wood fiber bedding (it only stated that it is 100% natural so probably not aspen) and I switched it for the expensive carefresh. Since then, I get the feeling that Oscar doesn't like it as much as he liked his wood bedding. He hardly ever digs now, but in the past when he had wood bedding he used to burry himself and then he kinda swim underneath his bedding (he liked it a lot).

Aspen is almost impossible to find so do you think I should use wood even if it is not aspen?
