Pooping mouse tail?

Hi,
My snake ate its first hopper last sunday. Near my snake last regular poop (i know its poop) was a mouse tail. I don't know if the tail was actually part of the poop or maybe a regurgitation next to the poop. The wail was in white and gooey stuff.

I spot clean my viv every two days but i might have missed it from wednesday, so i'm not exactly sure about the time she pooped/regurged the tail.

So is it possible he pooped a full mouse tail or is it a regurge?

Thanks guy!

pic would be helpful, but the tail may have come out relatively intact somehow.

Did you hold the mouse by the tail when feeding? It could have just been degloved and just happened to have been next to poop.

I sadly didnt think to take pictures. I did smell it thought and it didnt smell like the regurge i have had with my other corn a few months ago.

For the feeding i do carry the mouses by the tail. But i didnt come off during feeding. do you think it might have come off later and she regurged just the tail?
Should i treat it like a regurge?
