I'm a little confused. You said in the top post that he ate his first mouse...then in your next post, you mention that it was his first "live" mouse and he was eating f/t before that. I've never heard of anyone switching FROM f/t TO live. Or did he go through a fasting period and only came out of it with a live mouse? Some clarification would help us give better advice.
But as has already been said...every seven days is a fine schedule for a young bp.
