I just witnessed my male hedgehog pee and I'm equal parts confused and worried. He hid himself behind the running disk and next to a litter box. I moved the disk away to make more walking space, unaware what he was doing. He then began rocking/thrusting back and forth vigorously and soon after I heard a wet sound, like smacking lips. I realized that moment he must be doing his business and waited for him to finish, then when I've noticed no poo I touched the wood and it was wet. I didn't measure the time but it must have lasted at least a minute.
Is it normal for hedgehogs to pee this way? He used to use sanitary pads and I've seen him pee before on them, he would just freeze for few seconds second and walk away. None of this rocking back and forth or loud splashing.
