Does anyone have a preference for rat substrate? I have been using some "Track Side" pine shavings I got from a feed store but not sure if it matters to the rats. 3.12 cf and was about $8.
The other is made specifically for small animals and bought at Walmart but a little smaller of a package at 2.0 cf and about $6.
Should I just stick with the feed store shavings or get something like the stuff from Walmart. Lately I have been just mixing them together.
