I am so, so sorry for your loss, but please do not blame yourself.
You said in your other thread that Jezzabelle also goes outside, so this unfortunate tragedy happened whether you were mad at her or not. Jezzabelle knows how much you loved her and has forgiven you and will be waiting for you to join her when the time comes.

I pray and hope that you find comfort and peace in the fond memories you made together.

Rest In Peace sweet Jezzabella.
