Hey I feed my boa on mondays. This monday I feed her a small rat because I took her to a nearby reptile shop and they said the mice she was eating were too small. She ate it fine, just took a few minutes longer to get it down. Now it was quite a bit larger than her mice she was eating which did not leave a lump at all, and the rat left a noticeable one. The mice she would digest and perk up, exploring the cage and could be handled after 2 days. The rat lump is still there and its thursday. She is also acting rather defensive now and doesnt want to move much and stays on the heated side. This past saturday I noticed her eyes turned blue/cloudy and now her skin is kind of wrinkly so i havnt handled her since then. All of this is making me uneasy as i'm new to snakes. Her cool side is 75-78, warm side 90, humidity 68. Should I be concerned??

My camera is not the best by far but i do have pics of the lump.
