That's right; I have noticed no difference. but I still want to know if there's any toxicity if a mousie hogged out all the little pieces that went into a group cage. I'd gladly substitute something else if there is even a minor bit of toxicity. I just tried it on them since we keep almonds around as part of our attempt to raise good cholesterol in our poor old bodies (I'm 58 and Nate is 61; I raised my good cholesterol from 21 to 39 in a bout a year, and lowered my bad by 20 points!)
