Some time this week, I plan on feed my 1.5 year old ball a live rat for the first time. I've read a lot into this so I am prepared and do not plan on leaving the ball unattended.

With that being said, If my ball does not eat the rat, where do I go from there? How long until I attempt to feed him again and do I use the same rat? How often do I need to feed the rat and what can I feed it? Does it need any external heat (ie lamp)?

Thanks
