Ok, so my boys (8wks) have been on baytril for a month for URI. Two weeks ago azythromycin was added bc the URI went to a lower resp infection. That cleared up fine. Friday was their last dose of baytril and now they are on azythromycin alone for 2 wks, once a day. Woke up this AM to bloody urine in several places of the cage. Phineas appeared puffed up, tail felt cold to me, and clearly feeling miserable. Separated them to confirm the source of the blood and now both boys have each urinated and its normal clear/pale yellow. What the heck is going on? Gave Phin a dose of baytril before separating them and been syringe feeding ensure every few hours and his fur is back to normal. Not sure what to think....thoughts?
