So very sorry. We have had our kitty friend for 9 years now. It would break my heart to lose her. hugs.
I remember one time when my youngest, who turns 19 on Saturday, was about 12 and struggling in middle school with "mean girls". I got home from work one day and she was holding kitty and crying a little. I asked her what was wrong and she just said, kitty just brings her so much joy.
That about sums it up.
