Black Rat Snake

[Bouncingsoul]

This is my first post so please bear with me.

I have just removed (for the 2nd time) a fair sized black rat snake from a friends kitchen, where judging by the shedded skins under the sink it had been living for some time. If my friend did not have an elderly aunt living with him he would have let it live there but alas, he did not want to cause any undue heart attacks...

So I now I have a 4'+ fat bodied black rat snake. I did a fair amount of reading on cages, substrate heat etc. so I think I'm good there.

She(?) is super friendly after only three days in captivity, she lets me handle her with no problems and even spent a few minutes watching TV with me on the couch!

Yesterday she ate a mouse (live). It took her about 1.5 minutes from strike to finish, and afterwords she was "pacing" in her cage like she was looking for more food.

Ok so now my point/questions...

How much and how often to feed her? Since she is wc will she ever eat frozen? And if so how can I make that happen?
Her tail also seems really blunt, it isn't a point at all, kind of looks like a really small 2nd head, could she have had some trauma or is this normal?

Thanks in advance, and please don't yell at me for keeping a wc snake.
