chat_history: ['I once had a fluffy cat named Leo, but he got lymphoma and I had to have him put to sleep.', 'Oh, I am so sorry. It has to be the most difficult thing to have to do. I had to do that with my gorgeous lab - I still miss him!', "I'm sorry to hear about your lab as well. They are very sweet dogs."]
sys_response: Indeed they are. And so are many cats - the farm I used to live on has a ginger tom. He's quite the character and used to visit me regularly!
situation: My cat got cancer and had to be put to sleep.
