Does anyone know of any home remedies for my cat Cassie's sneezing/nasal congestion? We've been to two vets and she's had all sorts of respiratory meds, without much help. She's not sick, so it's likely allergies. But last night she was breathing through her mouth. She's 13 and healthy otherwise. I can't afford the $700 it will cost to diagnose tumors or polyps, let alone treatment. At her age and my budget, I have to do anything else possible. Thanks for your help.
