Yes on the training: beyond what She's a witch mentioned, our vet tech suggested petting Ireland with the chamber. I'd already been showing her the mask so petting her with the chamber itself was a good next step. I still do it when I'm shaking the inhaler for her second puff: Ireland likes to scent it.Then you can start the training now, you don’t need actual inhaler to start introducing the chamber to Kila, she can totally even breathe through this without the drug when she’s ready to. You’ll find lots of YouTube videos about this but if you have any specific questions, let us know.
It actually makes sense to me, as I don’t think that inhaled steroids will work if the oral ones didn’t. My vet did a similar thing, we had prendisolone first and only after we knew it works (and it worked immediately in our case), we started the fluticasone. I guess the oral steroids are somewhat stronger and vets don’t want to start the inhaler process (given the training effort and regular price) before knowing that it’s the possible long term solution. I’ve heard about many cats that were fine on prednisolone, but not on the inhaler unless much bigger than recommended doses were administered.
And that's very interesting about the oral/inhaled steroids. Ireland was never on any oral steroids, she just went right to the inhaled/fluticasone.
