When feeding pinky mice don't give them anything else with it the same night. Wait a day or two for them to start breaking down the mammalian tissue and then offer a couple night crawlers to soften the frogs stool. This helps prevent impaction or constipation caused by frog having difficulty breaking down the complex tissues of mammals. Our tissues are more dense so are difficult to break down.
Congrats on the new addition. I just picked up a new Green Ornata today.
