Hi and welcome to YT..

I cannot stress enough how much you need to get your baby to the VET....................... They can get dehydrated quickly and what your describing could be something like Pancreatitis that can be deadly. You cannot take chances with these little guys. If ther is an emergency vet in your area you need to take him now... tomorrow he will be worse.
have you taken his temp?? rectally ?? if it is more than 101 you must take him tonite. try to get some water into him, will he drink?? does he throw it up too? What does his stool look like in color does it look like normal?? what did the black stuff look like?? stringy, clumpy or what?

for sure if the temp is elevated he neds to see the vet tonite!!!!
PLEASE let us know what you find out.....
