Theophylline for asthma
My cat has asthma and we were having a hard time getting it under control. I first noticed sorta of noisy breathing last year, much like wheezing but a little different than you'd hear in a human. Then, she started getting respiratory infections and increased trouble breathing on a daily basis. Since we started using this, her symptoms are almost completely gone, she seems more energetic, and I'm a lot less stressed now because I'm not always worrying about her breathing.
