I'm so sorry about the loss of your kitty. Losing a furry friend is so difficult. I had to put one of mine down when she was 19. I'm also very sorry you had to deal with health issues as well. I hope things get better for you soon.
I'm so sorry about your loss, especially with the whole Raven thing happening. I have an 18-year-old kitty who is blind and deaf and on a lot of medication to keep going. I've only had her for 8 years (adopted her from a shelter at 10), but she's my baby and I love her so much. I know how it feels and wanted to offer some positive vibes.
