New Special needs kitten

[FORGETMENOTPETS]

Today we got a 8 week old kitten......mean as the day is long (cause he is hurt) X-rays showed a broken pelvis. Dr Wilson says he has a excellent chance to walk again  My problem now is to get his bowels working again. I used warm water last night as an enema and it worked. But his stool is hard as a rock anyone have any suggestion to safely loosen his stool? Please pray little Ozzie recovers. Karen
