Yoshimi lost her voice

[Koteburo]

Yoshi is an extremely loud (deaf) and very vocal cat yesterday she got a cough for about 1 or 2 mins and after that her voice was all scratchy and today barely any.
I'm in bed due to respiratory problems and laryngitis myself. started last week so I'm worried somehow I gave this to her. I know they can't catch colds from us but this is different a bacterial infection, im on antibiotics. So anyway I would hate being the cause of her being sick and worried about passing it to my other cats.
Yoshimi has good appetite and acts normally, no discharges or anything.
