While I have tricked an occasional Jungle into eating a rat periodically, my success has been limited. I have tried various scenting techniques and have even sewn mice onto a rats head with only limited success. Some will even eat the mouse and then regurgitate it when they reach the rat portion of the meal. We have the best success starting them eating with larger food articles. Fresh killed is the next option.
Live food is avoided if at all possible.
We keep fresh water available at all times. Water bowls are scrubbed out weekly, by my daughter when I can catch her. When housing animals in slide boxes we use newspaper for a substrate. It is plentiful in our house, clean, and easy to use.
