Hey guys, I have already posted about this on another thread and I could be over reacting but I am really freaking out about this. I am baby sitting a rainbow boa for a friend because it wasn't eating so i got it eating for him. Well, it ate 3 times for me every 7 days. It was given one fuzzy mouse. The whole time I've had it, it hasn't defecated once and it had a little bit of orangey yellow stuff on the stomach. I checked it today and it looks impacted and the discoloration has spread all over the stomach. I have a ball python of my own that shares a room with this snake because i am in a dorm and I am freaking out because I am worried that it could be something deadly that could kill both snakes. I told my friend that he needs to come get it immediately (he lives 2 hours away from me) and he asked me if i could keep it here until the weekend. I think it needs to see a vet but I have no vet that I could take it to. Can someone please help me and tell me if they think its a concern and what i should do.

P.S. Temps: 83 belly heat, 76-78 ambient
Humidity: 70%

Thanks,
A concerned snake owner
