Our roommate just leaves her baby kitten alone for extended periods of time. How would you handle this?

There are four of us living in a house. One of our roommates thought it would be a cute idea to get a baby kitten… but she doesn’t take care of him properly. Her room reeks (the smell emanates out to the hallway) and she leaves for the weekend (sometimes for 4 days at a time), leaving the kitten alone, crying in her room. My other roommates have been feeding him at least, but the problem is, this isn’t anyone’s responsibility but hers. It’s at the point where I almost feel like calling the Animal Control board and having them take action.

The solution may seem like a “no-brainer” here but I really don’t want to cause any issue between anyone here. We all get along here for the most part and I really enjoy living here otherwise, but I can’t stand to see animals neglected like this. On the other hand, the animal isn’t ours so we really shouldn’t be obligated to pick up where our roommate decides to leave it. How would you guys handle this?
