I do think that meal is big for this BP. Can he handle it ? Possibly. But why risk it...

Its not like he is in the wild and has to take advantage of any meal that may come along because it may be the last one for a long while.

That said, the BP's I used to have could take xlg rats without a problem. Well, the females anyway. One of them (4500 gr. female) took jumbo rats like candy
