can you hurt the corn snake by giving a mouse too big? my corn is feeding on large mice but the other day she had a mouse that i even thought was slightly big. she ate it fine albeit a bit longer than normal. if it was too big to manage im sure the snake would leave it wouldnt they?
Yes you can harm them and unfortunately, no they wouldn't necessarily leave it. A maximum size would be 1.5 x the girth of the snake, but preferably about the girth of the snake.
Just feed the snake a mouse that is the same thickness as the thickest part of the snake. When fed, the snake should have a small but noticeable lump where the mouse is.
one of the problems with feeding over-sized prey items is that the snake can't actually digest it quickly enough and it can go rancid in their stomach causing regurgitation. i'd just keep an eye on her though, make sure the bulge from the feed is going down rather than getting bigger (gasses as the food rots inflating the gut) and maybe give her an extra day or so to digest it before handling otherwise regurge is a possibility again.
