I've only just read your thread about Matilda, having not been online for a while. I'm so, so sorry to hear what has happened to your beloved little cat. Believe me, I do know how you feel - my darling Bat cat went missing last year and it was a month and a half before I found out she had died. I will never know exactly what happened to her, but can only hope she did not suffer, as I dearly hope your Matilda did not either.
Great big hug to you. I hope, like me, you find comfort from the good wishes of all the wonderful people who come on this site. It helped me so much.
