Would you be concerned about this feeding activity?

My 0.1 Butter is around 130g and taking rat pups since I got her. She normally eats every 5-6 days depending on my work schedule. Today was day 5 and she took it within seconds. I have noticed she does not completely kill her prey before she consumes it. She will start taking it down if it is still moving and squealing!! None of my other bp's do this.

It seems odd, but she has done fine so far. I just wondered if this is fairly common or not and if I should be concerned?

TIA.

I've heard of it happening a few times. I think this usually only happens when the prey item is very young/weak. She shouldn't continue to do this for her whole life, that's for sure.
