Hi, amoxicillin can be used in kittens but how do you give it ? I have witnessed some owners doing more harm then good by administering oral medications to kittens. I would recommend to see your vet so they can be started with a more effective, safe and fast acting injection and then you can continue at home with some oral drops for example. The dosage in kittens would be 10 mg per pound for 5-7 days. Hope this helps,

    Amoxicillin will help treat or prevent secondary infection. If the sneezing is due to viral upper respiratory infection, the amoxicillin will be ineffective in treatment. You could dilute it with water but without knowing the kitten's body weight, it would be impossible to determine the dilution (so you have enough for any treatment) as well as the dose. Ideally, the kitten should be examined by your veterinarian. He or she can dispense medication that is already diluted or reconstituted properly if indicated. Amoxi-Drops or Clavamox Drops are frequently dispensed to treat infection in cats and kittens.
