Updating to say that Christine Perfect got a mostly clean bill of health yesterday and was finally heavy enough to have her first round of vaccinations!
And then she insisted on riding my shoulder all the way home.
We did do an x-ray of her head to rule out any traumatic brain injury causing her wobbliness and found a few darker areas on the scan that the vet couldn't immediately explain, but she said all visible structures looked well developed and so long as Steen is being an otherwise normal kitten to just treat her as such, and also she was so good for her scans the vet didn't even have to hold her on the table, she just stayed positioned and purring. That's my girl. /proud
