Spoke with the breeder and he thinks we fed to large a mouse. He handled hopper mice easily so 2 feedings ago got a small adult and he got it down with a little difficulty but did ok. I'd say just slightly larger diameter than largest part of body. Everything seemed ok so last feeding got the same about 8 days apart. He was going into shed and I was a little reluctant to feed but my understanding was that he might eat and might not so I thought I'd let him decide. This time it almost looked like he wanted to eat and changed his mind about a 1/3 of the way down. Started coiling around and I think he was trying to back out of the deal. He did eventually get it down and 3 nights later it came back up and 10 minutes later he was dead. I will never attempt a feeding while they are in the blue again. So we are cleaning everything today and have some f10 in route. Going to sanitize thoroughly and get reset. Breeder has several 2 and 3 gene morphs that he was going to keep for himself that are no longer juveniles. Enchi pastel and lesser pastel are 2 he spoke of specifically and said he would make it right. Don't know for sure exactly what that means but he's definitely trying to help out. Hopefully this will give us another shot at a long time friend for my kiddo. I will try and post pics of habitat once we get everything set back up so that I can get suggestions or critiques and make changes if warranted.
