So good news, I went ahead and got a live mouse from the feed store and that did just fine. I’ll definitely be keeping her on these for a while before I transition her to frozen thawed. I had one of the store owners recommend that I block off part of her cage to shrink it down, which I think I’ll go ahead and do as well (if not completely transfer her to a new tub) to make it smaller. I also got her weighed finally, she’s 266 grams.

thanks for your help everyone, I learned a lot and I appreciate all of you taking the time and effort out to help me!
