Hi, my cockatiel of 12 years died a couple of days ago. About 2.5 years ago, he had a spell where he was breathing heavily for an afternoon. He stopped doing it, but we took him to the vet. The vet did do a fecal test and swabbed his throat and cultured it, and was normal. The vet said perhaps he had a seed hull lodged in his throat, and he worked through it, and to shower him frequently, that the humidity may help his throat/lungs.
Last week, he started to do it again, off and on. No other changes in appetite or behavior. On Sunday, he was acting normal, but a little heavier breathing...and then all of a sudden after his shower, he was on the bottom of his cage. He got worse and worse and died 3 hours later.
We moved since then, and now our closest avian vet is 2 hours away, so we did not have a place to take him for a necroscopy. Any ideas as to what this could've been? I thought he was going to snap out of it like last time. Would there have been anything one could have done at that point when his breathing was so labored? I feel terrible, he was my little buddy.
I do have another cockatiel of the same age and a timneh african grey parrot that both seem to be fine. Thank you for any ideas.
