My Frankie is having his second bout in 4 months with a bacterial infection. I don't understand why he has it again. His cage is immaculate and his food and water is changed twice a day. He's now on Enrofloxacin 0.04 mil once a day. His dosage is so tiny I can barely see if he's getting it down. He's all fluffed up and sleeping a lot but he did eat quite a lot this evening. Has anyone used this antibiotic and does anyone have an idea why he's getting sick so often. I love this little guy. He's a rescue so I don't know how old he is but I've had him for 5 years. Any info would be a huge help.
