Thanks for the quick reply Matt. the 1/4" is on the soft furs and mice only and 1/2 for the rats so I should be good there. the 23% I get for 13 a bag, and is all I can get. I talked to chuck From the Kent HQ and he told me I prolly couldnt get the 19% because who ever bought it had to by a min. of 80 bags. hopfully the 23% works good and they like it. are your "cubes" alot bigger than reg. lab block? these are about the dia. of a quarter and about 1.5" long. seems like would be hard for them to eat. we will see though.
