A few years ago one of our cats died after we had her for 14 years. We were all heartbroken and devastated by her loss. We noticed something was wrong on Thursday, took her to the vet on Friday, and she died late Sunday night.
The night she died, I sent everyone to bed and I stayed up with her. She kept getting into the bathtub and lying down as opposed to a bed we had set up for her.
Just before she died, she let out a horrible scream and went into convulsions. Then she just stopped breathing.
I never told my spouse or kids about that last few moments. I just told them she just slipped away. I still want to cry every time I think about it. I will never tell them about that.
