Ah, if Nilla is scratching her ear a lot and tilting her head from side to side, then is does sound like she may have an inner ear infection or ear mites. Take her to the vet and have them look at her ears, and maybe to a ear swab and look at it under the microscope. You want to get that nipped in the bud as soon as possible to avoid any type of inner ear damage or loss of hearing.
Can’t wait to see some pics! Glad to help.
