i upgraded her cage recently, its huge now. but the guy at the store as well as my girlfriend convinced me to get the brown mulch type stuff because my girlfriend thinks it looks better, and the guy at the store said its easier to clean.
i used to have the green mat stuff, i would just take one out and wash it and replace it with another whenever needed.
i was told with the mulch you only need to spot clean. is that accurate? so far the information i've got from any pet store as been incredibly wrong. this guy seemed to know what he was talking about, but now i'm not sure. she had no problems until i got this new stuff.
