I think that would be all the more reason to see the vet. Tell him about the insulation possibility so he will have all the facts when evaluating this kitty. He will have the knowledge and expertise to figure it all out, but any information you can offer will certainly make it easier and quicker = less suffering for your kitty. Please keep us informed on his findings and her progress. Being a persian, she may be more susceptible to problems caused by the insulation.
This last year I have had respiratory problems myself and I have been amazed at the relief my doctor has been able to give me. I thought I was pretty knowledgeable about medicines, but had no idea what is available when needed. I'm sure the same holds true with veterinary medicines.
