The first thing I noticed wrong with my Mittens was that one pupil was larger than the other. They gave her steroid shots and antibiotics in case it was an infection. That didn't help, so got X-rays. A small spot appeared near her lungs, which they said might be cancer or she might have inhaled liquid. Then she quit eating and was throwing up white mucus. Ultrasound showed kidney infection. More injections and pills to make her want to eat, and still she wasn't better. Did another X-ray about 3 weeks after the first one and the spot near her lungs had grown considerably. Took her to LSU vet clinic which specializes in oncology 3 days ago. She had a fast growing cancer that had gotten into her bones and spread through her body that fast. They said they could do rounds of chemotherapy, that would require a lot of hospitalization, but might only give her 4-6 months more to live. Plus, it would cost several thousand dollars. I wasn't going to put her through all of that. She already hadn't been eating for a week or more. Picked her up Thursday morning and brought her home. She was so happy to be home. Gave her one more loving night here, then took her in yesterday to be put to sleep. Broke my heart. She was my little shadow. I had just lost my Poppy in February to intestinal cancer. I have two babies left and am praying they don't get sick. Spent over $3000 in vet bills in the last three months trying to save them. I hope your baby recovers.
