Can you solve this legal mess?

A man and woman lived together in an apartment. She had a cat that she paid $45 to buy and he has a python. She spent $2500 on the cat for chemo to treat feline leukemia and left it to recover on a pillow next to the python's cage. They then left for work and the latch on the cage was secure. Later, the cleaning lady let herself in to clean. A few minutes later, the maintainence man came without prior authorization to check on something and the cleaning lady let him in. He accidentally bumped the cage and jarred the latch loose. He didn't notice it but the cleaning lady did and said nothing. Both left later leaving the latch unfastened. The couple returned after work to notice the python loose and a large lump located in the middle of its stomach. The lady was furoius and was ready to sue! She suffered for several days with mental anguish and will ask for $5000 extra. So, tell me. 1.Who if anyone is liable? And. 2. How much can she recover in damages if she gets a judgement?
