I'm so sorry that you are going through this...it's such a terrible feeling. I've had to say goodbye to many pets over the years and the clinic/animal hospital is not a bad environment to say goodbye if your precious kitty is suffering. Your kitty will not know the difference, all they know is that they are unwell. Vets are always compassionate and give you all the time you need to say goodbye before and after. I've had many offer me reassuring words when I question if I'm making the right decision or not.

Again, very sorry that you are going through this.
