Well, since I was 11, I have had a cat named Sassy (original, right?). She is nearing 15, and her health is failing. She is diabetic, has hyperthyroidis, and kidney disease. And while the vet says she isn't in any pain, she will be in the next few months to a year. When she starts showing signs of pain, it will be time. I am very sad, I am just trying to make memories of her and the kids together.
On another note, our Christmas kitty, Cleo, was spayed and had fatty tumor removed and now she is good to go until her vaccines next year.
