I have a dinker that will only eat live mice
She has to be left alone and in the dark
She will only eat two a week

It is kind of crazy because she is just over 700g and will not look at any size rat. I even put a hopper rat in with my mice overnight and it didnt work
I have only gotten one rat in her and it was when I caught her in the final swallow of a mouse, I had a pre-killed hopper and stuck his nose in her mouth while she was open. I was worried she would gurge it but she didnt. She did smarten up and will freeze if there is any movent around her tub
