This August my 830g normal female started to refuse meals. I tried every week for about a month and then switched to trying roughly every two weeks. Well last night I tried to feed her (f/t) and she seemed interested, but wouldn't strike so I left it in her hide with her over night. This morning the rat was gone! Im stoked. I was a little worried but because her weight had remained roughly the same and she didn't show any signs of negative health, I figured it was a dreaded hunger fast.
