I got a great deal on a huge bag of aspen, put it in the tri-plex where my little ones are, and they have abandoned their hides. They now burrow into the aspen, and even under the newspaper. They have eaten since their arrival, and they pop out like sand boas to snatch up the fuzzies. When I was putting it in, it was like spagetti, it just seemed like there wasn't enough, and now there is about an inch in there, and I haven't seen them since. I guess my concern is respratory problems from the dust. The temps are fine. Any feedback would be appreciated.
