Hello everyone!.. In a previous thread I asked you about my rattie's med and for how long she should take them..After completing the 6 week course of Baytril and Zithromax, even near the end of week 6, my rattie starting making the usual resp inf-noise...I consulted my vet and he seemed kind of clueless on what to do next, eventually telling me to just let her be. But she's still active, and curious and she has a steady weight and I just can't give up on her. I was thinking of trying Zithromax and Doxy combo, in the past, doxy had worked well for her. I honestly went through all exotic vets in my area and they all don't know exactly how to treat a resp inf on an elderly rat, they tell me to let her succumb from this. I can't give up yet. Not until I can see that she's not living the best of her life. I've read that Zithro and Doxy are a good combo, has anyone had experience with this? Did it work for them? And since she the resp inf doesn't seem to go away, should I give her meds for the rest of her life? Thank you everyone for your support. You're really a great group of people.
