Ah yes, the bloated pacman belly. You'll have this from time to time. A nice round belly is okay for a pac. If he has a somewhat firm bulge to his right belly, he is constipated. A honey bath with luke warm dechlorinated water and about 3 drops of plain honey in which you soak your baby for about 15 minutes usually does the trick. If this does not help, a gentle trickling of dechlorinated water over his vent (rectum) often stimulates a good peeing and often a good poop. Just a small stream. They are not really favorable to the water over the butt trick. After his honey soak, rinse his dish out well and give him a regular plain dechlor water soak to remove residual honey from his back and belly. This usually works. He is likely not used to being handled yet, but if you don't get any results within a day or two, I let my pac hop around in a bigger plastic tub, and the activity usually gets him to go. I usually just put the honey water right in a plastic tub, let him hop around a bit, then place him back in his home in his own water bowl. Works like a charm. Sometimes takes a day for him to go though. I almost always find a good poo by the next morning .

Depending on how full or firm his belly is is a good way to determine if he should eat again yet or wait a day. Is his belly still full but soft or more firm?

Btw, he's adorable! What a cute face! I love albinos . Great find .
