Brownie is 7 going on 8 years old. He was on antibiotics in July and again in October, some infection(one I had never heard of). but was treated with Baytril(it was in his nasal cavity). I will suffice to say he has chronic breathing issues which I keep a very strict eye on him. Well today he consistently kept tilting his head upwards. He is eating good and everything else seems good..this is just an out of the ordinary behavior for him. I made an appointment for Monday with the vet, earliest I could get. any ideas tips suggestions. I have a humidifier in his cage. worried bunny mom. he is older and I lost his mate Misty last year.....and she was about this age too.
