When every single vet in the practice has seen your cat for the same issue at some point over the past 6 months, you know it's been going on for far too long. Fair enough it's not a huge practice, but there's 5 or 6 vets that work there at various times!!!
Anyway, so I took Indigo back in yesterday. She's had a blood sample taken to be tested, a highly expensive test that will possibly narrow down the allergen a little (so is it dust related, is it pollen related, etc...) which will lead to further, more specific, and no doubt more expensive tests to try and narrow it down still further. She also had an antibiotic and an antihistamine, so is a bit battered and bruised at the moment.
I'm hoping the insurance will cover it (must get onto them) but if it doesn't I'll find the money because being constantly itchy must be horrid for her.
