I buy live and then pre-kill my rats because its easier for me in my situation when it comes to feeding my BP. Sometimes I may buy smaller rats then I need and grow them out to feeding size (aprox 140-160g rats for a 900g BP). I feed the rats a mixture of pellets and a mix of dried seeds that look like bird seed a little. Both are meant for rats that are kept as pets. Their water is extremely pure well water that's free of all chemicals so I'm not worried about that.

Is their anything I need to careful about feeding the rats during this time? Are their certain foods in a rats diet that can be bad for my BP?

Keep in mind that I allow my rats to free feed right up until the moment they become food so their will be undigested food in their stomachs.

Before any one asks my BP seems very healthy and is shedding about once a month (2012, female)
