I recently switched my rats from a seed mix to a lab block because I noticed they weren't eating any of the healthy stuff. But what I've noticed is that the black rat takes all of the blocks from the bowl and dumps them in the corner where she poops, untouched.

Anyone else experienced this sort of thing? I'm assuming they'll eventually get over it and eat them, but I'm afraid the brown rat, who I've seen munch on them, isn't getting to them before the little nigger takes them all and dirties them.
