I am wondering whether to try Zoologix panel PCR test for upper respiratory pathogens for my kitty who seems to be permanently afflicted with blocked nose and sneezing. She has not responded to antibiotics nor antiviral (famciclovir) treatment. The only thing I could find out about Zoologix was someone asking here about them 10 years ago but no-one reported back. Their panel test costs just under $100. The vet wants to charge $300 which seems a bit steep for something that may not tell me anything useful anyway.
