Hello for the second time today

As I mentioned in my previous thread, today was feeding day for Fírnen. However, instead of feeding him my last fuzzie mouse, I decided to go to my local pet store and buy some f/t small mice.

I weighed the mouse and it was 7 grams. This weight sounded perfect to me, as Fírnen is currently at about 71 grams. So then I thawed and heated the mouse for him, and he took it immediately.

He swallowed it in a few minutes, throughout this process I was worried because I had never watched him eat something that big before. I'm almost 100% sure that I'm just being paranoid but I still want to ask, how much resistance is normal when a bp is swallowing a meal?
