Hey guys

I have been feeding Ruby out of her viv since I had her and for the last 4 weeks have been feeding her on XL mice. Since then she has refused to strike when I present it to her and I dont know why? After placing the mouse in her viv, she then eats it! Is she getting lazy; always being fed on FT? I am also planning to move her on to weener/small rats next week and am worried that if she's not striking, will she still eat a FT the way she has been and still make the change over or shall I try a live? she is 400g.

Thanks
your help is most welcome
