I have a baby squirrel (I'm guessing around 2-3 weeks old) that I've had for a little less than 48 hours. He was found on the ground below his nest. Reuniting with mom was unsuccessful. I rehydrated him and started him on diluted HGMF+. He is very energetic and eats well, but has not yet pooped since I found him around 36 hours ago. This morning his belly seems larger and more firm than it did yesterday and I'm concerned he may be bloating. I have been giving him pedialyte between formula feedings for hydration. I've also done warm bath and massage with no result. He's peeing like a racehorse though. What can I give him to ease the bloating and break loose his constipation??
