The vet thinks that in all probability, Lucky died of Laryngeal Paralysis, that her upper airway collapsed. I have read all the threads involving Lar Par, but I think I attributed much of her symptoms to old age. Lar Par did cross my mind, but I also assumed any treatment would be too stressful on a 13 year old girl. What I did not anticipate was that she would ultimately suffocate. The last two hours of her life were so stressful that I will never forgive myself. If there is any way to prepare yourself, do so. I would not wish this on my enemies, much less my cyber friends. Sorry to be a Debbie Downer but just saying, be aware.
