Just got Mazie home from the vet. They did an xray of her chest and said that she has fluid in her right lung and a nodule in her left. It is most likely cancerous. I have her home for now, but they recommended euthanasia.
My husband and I are devastated. She's our baby. Our oldest. I got her for him in 2008 when we were still living apart. She's been with us almost as long as there's been an us. What a hole she's going to leave.
