You have not failed Boris, Jenn.
Sadly like we humans our Cats go at different times.We have had Benjamin James , Almond Rocca , Precious and Pouncer pass on before they were 12, and it is so hard not to wonder what I did wrong.
But My Vet said that most of the time if they pass on in a good home enviroment, that sadly it was their destiny.
We are sending prayers for you and now Boris now has her wings of Silver and Gold and will now join Our Awesome Eternal Pets and Companion Angels in Geneva Switzerland.
Please be comforted by the fact that you will be together in love.
One Fine Day
