Murphy - Constipation Issues

Hello all. I couldn't figure out for the life of me what happened to the website, scared me to death b/c it is so needed! So, here we are.

Is it common for diabetic/pancreatic kitties to end up with IBD? Murphy has become constipated, and may have to get an enima this week. I'm considering putting her on Miralax -- she just hates the sweet taste of Lactulose. This obviously adds insult to injury so I need to get on the band wagon with these before it causes more issues. I was wondering if anyone else has experienced the same thing.
