My favorite so far is Durgin and Crowell, but the generic brown bag from the feed store are ok, TSC is expensive considering how much smaller they are. This time all thatni could get was a Canadian brand that says “wood shavings” they were almost wood chips, they had an unpleasant odor to them i suspect was mixed hardwood. I had taken for granted how much odor control was gotten from the pine shavings, I certainly appreciate good shavings more than ever before. These are as about as absorbent as wax and after one night the smell was unbelievable.
