Does he eat still. If he does trygetting the GI starting things eaten like papya, fresh pineapple,canned pumpkin. Make sure he is drinking plenty of water andis getting excercise. You could give his tummy a massage toget things going also. If he isn't eating, then nutrical canbe used to stimulate the appetite. Though I think if he isn'teating, you are going to syringe feed him some of thepumpkin. If he isn't pooping, then you need to get it startedagain as soon as you can. If the poop isn't coming for near aday, vet time.
*edit* I just reread your post, you aren't talking about dirrehea are you?
