I may have fed my corn snake too big of a mouse...
I picked up a mouse today and all they had were large adult mice. Once I got it home it looked pretty big so I weighed it and it's more like a jumbo mouse. Although I've been feeding her small adults I went ahead and offered it. She grabbed it but then let it go which is very unusual for her. I was concerned at this point that it was way too big for her and I probably should've taken it out but I left it in there and eventually she got it down. It left a huge lump...
As of now she's in her warm hide but I'm concerned about this meal size. Does anyone have experience with feeding too big a meal and if so how did they do (any regurgitation)?
*She's a little over a 1 1/2 years old
*She weighs 217 grams
Thanks so much!
