I have a female rat who has been on Baytril for over a year. The reason for this is we treated for resp issues but she continued making this clicking noise with her nose. She's been on doxy + Baytril and other combinations. I could finally get Zithro to see if it would help clear it since it seems like a nasal thing. She's been on it for a while now but still makes this noise. The vet took an X-ray to see if her heart and lungs looked alright and said everything was fine. While she's resting, I can't hear anything. Her nose starts clicking when she gets overexcited. Like when she play fights with my hands. Should I try a combination of Zithro + Baytril + Doxy? It seems way too much just for a little sound coming from her nose. Im thinking of stopping the medication to see if it just stays stabilized and get back to it if she starts sounding worse. Is this a good idea? Also, has anyone every tried CBD oil to ease chronic resp complications? I'd like to know your experiences with it. Someone reached out to me saying that CBD greatly reduced complications on their rat with chronic issues and I think I'll be trying this with this female I mentioned plus an oldie that is on Baytril + Zithro as a maintainmence dosage ( Just Baytril was no longer working ). Edit: The female making the clicking noises is overweight. Could this be a reason why? We're currently trying to get her to loose weight.
