I'm so sorry OP but your cat sounds as though she was very well loved.
One of our cats died aged 5 from a horrible kidney disease. The vet couldn't do anything to save him and we were devastated.
His twin sister developed a heart issue when she was 8 and had a massive heart attack when she was 10. We managed to get her to the vet but there was nothing to be done and they said the best thing was for her to be pts.
We had another cat who we had taken in as a stray, so we weren't quite sure of his age but the vet thought he was fairly young when we got him, maybe about 18 months. He had a digestive issue which was treated with medication but after about 5 years the medication stopped working and he died. That was 6 weeks before our cat with the heart problem died. We were devastated because, although they were both ill, we didn't expect them to die.
Prior to those 3, we had two cats that lived to 17 and 19 respectively but neither of them had a great quality of life in their last year.
We have currently got two cats who we are hoping will live into old age, and a puppy who will hopefully live until 13/14.
But one of the harsh realities of owning pets is that you will outlive them. All we can do as owners is ensure they have the best life when they are with us.
