2 Year old Corn, 411g. Stopped eating. Puberty?

3 Week mark and still not eating. When is it cause for concern?

keep an eye on your corns waight, my 8 yr old corn rexy hasnt eaten in 5+ weeks, she was 641grams then laid eggs, so obv mine will have lost waight but they can go upto 3 months with out eating but if theres a dramatic loss in waight i would make sure your temps are correct and make sure there is enough hides atleast 2 and fake plants to make him/her feel safe, as it can stress them out and they will go off food, if everthink is near to correct and theres a dramatic loss in waight i would then visit the vets.

Ok, so strange behavior. I left him in the feeding tub with the mouse for about 25mins. He kept looking for a way out. Then started doing silly things with the mouses body like trying to crawl under the paper towels where the mouse was, and pushed it around the tub for a while. Left it alone for a bit. But eventually ate it. So thats a relief. I will try again in 2 weeks.
