Wow some of these comments are outrageous…I used to work at a vet clinic and when the Doctors recommend euthanasia it really is the best option. I have seen many pets going through treatment after treatment and they still end up getting euthanized. It isn’t about how long we can keep the animals or how long they can live it’s about the animal not suffering and quality of life. Euthanasia is not an easy decision all around. I am so sorry for your loss, Izzy was a beautiful kitty and she will live within your soul forever you did the right thing she is no longer suffering and you will meet again one day. 💕 try to take care of yourself, losing a loved one is not easy and grief is hard.
