    Help identifying gender!

    Hi, I recently rescued a few guinea pigs. I need a little help to figure out the genders so I can act accordingly. Thank you, hope the picts are good enough!

    See if http://www.cavyspirit.com/sexing.htm helps you any.

    A guinea pig penis has a bone in it, called a baculum. If you put your finger crosswise just next to it and rub back and forth, you should be able to feel the bone rolling under your finger. No bone, no penis.

    Or, you can press down and toward the feet and see if you can extrude a penis.

    My thoughts, first is male, other two are female. If I am correct you will be able to feel the firm line just above the genitals, that is the bone bpatters described, on the first one but not the other two.
