Aloha! You're speaking with Dr. Michael SalkinI've had rats as pets throughout my life and I'm afraid that I can't be too encouraging. Delgato's breathing suggests the pneumonia of murine mycoplasmosis although Streptococcus pneumonidae and Corynebacterium kutcheri are also common pathogens. I've been able to address these infections best with a combination of 0.05ml of the injectable enrofloxacin (Baytril) daily and doxycycline (5-10mg/kg every 12 hours) for a minimum of a month - or indefinitely in severely affected rats as Delgato seems to be. Your vet - even if not a laboratory animal vet - should carry the enrofloxacin injectable and doxycyline (Vibravenos, Pfizer Animal Health is a long-acting product and more convenient to give by injection at 70-100mg/kg every 7 days) and be able to dispense enough for you to treat Delgato for a prolonged time. Please respond with further questions or concerns if you wish.
So is it serious? Should I take him to a vet right away or can it wait until morning?
ok thank you
he's doing a lot better we caught the sickness early on so he should be fine. The doctor gave us a week worth of medicine to feed him and then we have to go back in for a follow up. But he's been eating, his breathing is getting better and he's becoming more active.
