I'm watching a friend's cat and she has trouble breathing, sounding like she's snoring/slurping constantly ("nasal stertor").
Apparently this is "normal" for her. She's always been like this, and she behaves normally otherwise, but it would be nice if there were some way to improve the symptoms.
She's had surgery for nasopharyngeal polyp(s?) and antibiotics to clear infections. Her nose is constantly plugged with grayish mucus and she breathes through her mouth.
Expectorant like Bisolvon or Guaifenesin?
