Sounds good that it is healing.
I agree with Stewart Reptiles that people don't have to be afraid of feeding live if that's their preference.
I prefer not to and I feed all my animals F/T from the time they are young (and frankly my Boas and Corns could care less). BP's can be picky but you said F/T isn't available in your area. Does that mean you want to feed F/T but feel you can't? If you didn't know, you can order F/T online easily and it's much cheaper.
If defrosted properly and offered properly, many BP's will switch. I switched a ten year old wild caught BP to F/T a while back and my BP takes F/T with no issues (I've had my current BP for almost 8 years now and she's happy as a clam eating F/T).
Having said that, if live is what you are into, that's fine, and sometimes damage can occur. However, if you are sure to watch and make sure the BP takes the rat and deal with any injuries, that's fine too.
How big is you BP and what size rats are you feeding? I only ask because if your animal would do well on small rats, but you are feeding mediums, for example, which your BP may also be able to handle, a smaller rat might pose less risk and be easier for your BP to overpower. I am not a pro here, as I haven't fed live in 30 years, but I think I've heard that elsewhere. Someone please correct me if I am off base here.
