You should give your cat the Albon oral suspension as per your vet's instructions. 12.5 mg/lb is the daily recommended dosage. This is according to the cat's body weight. An initial dosage of one teaspoon per 10 lb body weight should be administered. Follow this up with the 12.5 mg/lb dosage every day subsequently. The treatment can go for up to three or five days. This, however, is not a fixed timeline and can be altered. It will ultimately come down to the effectiveness of the solution, and the dosage your cat is on. A lot of it depends on how your vet instructs you to use the Albon medication.
