I'm so sorry about your cat, she's beautiful...
I have a cat w/ diabetes and cancer. His age is unknown, he was a stray who adopted me about 8 yrs ago (vet estimates he's 12 - 14). Luckily working from home means I can give him his insulin ($300 a month) 2x/day and care for him. Every day is a gift that he's still here. He was only supposed to live 3 months from last July and he's lived a year. It's going to break my heart when he's gone.
I agree about cats and vaccines btw. I lost my other cat to a sarcoma that began at the vaccine injection site from a rabies shot.
