Force feeding after only a month?Not always the best idea....
I suggest trying other prey items, it took me 6 weeks and multiple different f/t prey items, and then an extra week when she refused a live rat fuzzy to see that my picky baby girl only wants live hoppers right now. Force feeding is completely unnecessary at this point. Try a f/t hopper mouse this time, if that doesn't work try and adult mouse, etc etc. If he/she refuses after a couple more attempts, try a live hopper. I don't suggest force/assist feeding unless completely necessary.
