Hi guys. My coastal was the same..... didn't want to eat. it got to the point that I was gonna have to have him professionally force fed, they suggested trying live (which I'm against - but not going there) but leave the live food in a container for a day or two - nice and stinky, then pop in the cage. Well, after 4 weeks "Lunch" ( sub adult mouse) had his own food bowl, water, etc. (My lovely brave coastal vanished as soon as Lunch came around, but at the end they were sleping together in the hide cave.) anyway, one morning, Lunch is gone. Next feeding time, defrosted food goes in the old container for a few minutes, and shaken, then offered to my coastal. First time in nearly a year, he actually strikes and then eats!!!! it's been 4 weeks now, and he has eaten every week!!! Fingers crossed it continues......... might work for you..............
