Calculating Baytril dose. If we are looking at a dose of 5mg/kg/day and the cat is 6lbs. Remember there are 2.2 lbs in a kg. Then here is the math...

6lbs divided by 2.2 = 2.73kg
(2.73kg)(5mg/kg) = 13.63mg per day

This is the difficulty when there are not great ranges (dogs have a wide range which would make a dog dose at 13.63mg to 54.52mg). The tablet is 22mg so 11mg would be just under the 5mg/kg/day mark. 22mg is 61% higher than 13.63mg.

at 5lbs of weight, the dose of Baytril at 5mg/kg/day is 11mg which would be half of a tablet.

Has repeat blood and urine tests been run? If so, how do they compare to the previous tests? PM me if you need.
