Carmella's death was really awful. We still feel guilty about it. One night, after days of her not eating well and acting weird (spending a LOT of time outside all by herself), Carmella fell in our house. She was still alive, but was never able to get up on her feet after that. I spent the rest of the night crying and trying to get her to go outside or eat something, but all she did was lay there, breathing heavily and not doing much else.
The next morning we made the hard decision to call in the vet and have her come to our house to have Carmella PTS. We spent several long, agonizing hours waiting for the vet to come; meanwhile, Carmella's breathing grew more labored and (this was horrible) we could feel all of her extremities growing colder and colder. Anyhow, long story short (too late), when the vet finally came, she told us that Carmella's heart was barely beating and it was really difficult to find a vein she could use for the injection. Shortly after that, Carmella basically died on her own. So yeah, she died naturally, more or less (she did have a bit of the injection), but it was just terrible.
It was awful. I wish I had begged the vet to come the night Carmella fell, because watching her suffer like that was definitely the worst thing I have ever had to do in my life. I know from that experience that if Flora ever begins to show suffering like that I will NOT delay giving her what she needs. No way.
