TRIGGER WARNING: Putting this video out there for general knowledge. This is what lung cancer in cats is like, and it's awful.

I originally taped this to send to vet because of concerns with her breathing. (I did not want to stress her out by bringing her in again unless this was her last visit, as she'd already had lung xrays at this point.)

Three years earlier, she had been diagnosed with breast cancer on a mammary gland on her left side and had all the mammary glands on her left side removed. She had 3 years cancerfree, but then it returned in 2018 to her right side, and she had a second surgery, from which she recovered well. Unfortunately, the cancer had metastasized to her lungs after the second surgery. This is 3 months postsurgery. She lived another 2 weeks after this. We kept her quiet and the saddest thing was to NOT pet and comfort her, as you can hear and see here, it made breathing difficult for her. She progressed quickly, and we did not let her suffer far beyond this point.

She was the best cat.
