Hi,
For how long has she had this balance problem?
Sometimes balance problems can be the result of vestibular disease. Do you notice if your cat's eye movements are abnormal at all? Vestibular disease can clear up on it's own within a few weeks with or without medication.
Is your cat vaccinated and up to date on her vaccinations?
When the vet checked her ears, did he swab and test for infection? Did he look into her ears with an otoscope (the pointy thingy)? Does she have any blackish-brown debris in her ears that look like coffee grounds? This could indicate ear mites. Did he say for sure that she doesn't have a middle or inner ear infection?
Trauma is a possibility (a head injury). Ear infections and ear tumors are possible (tumors do sometimes occur in young cats).
I think blood tests and x-rays might be very helpful towards a diagnosis (I'd do one at a time, of course--blood tests first). The following websites may provide you with helpful information re: paying for vet services at a discounted fee or using a credit card especially for vet visits (care credit):

I hope she's feeling better soon and you're able to get some more testing done, if she's not! Please keep me posted on her condition. Thanks!
