This isn’t exactly the same condition, but it still made me smile:
Is this your cat you’re talking about here? I’ve read about cats who are ataxic but never actually known anybody who has one. And, I’ll have to google 'chantilly’

Unfortunately no, just something I found on the internet and was happy to find my spirit animal 
I googled Chantilly cats, they are renowned for being very friendly and likeable.
I’ve only ever had one pedigree cat, a Burmese, she was loving and it was heartbreaking to part with her. We were moving and it was going to be difficult to keep her in, she was a house cat and I worried about her safety.
Since then we’ve had a succession of stray cats🙂 Three lived until their late teens🙂 Our current cat has been with us 2years, we were told she was around 2/3yrs old, our vet thought 12yrs old was nearer the mark😳 xB
