I am fostering six 5-6 week old kittens and they are all sneezing and I know I need to give them some lysine to try to nip this in the bud. I have 500 mg tablets and need to know what the right dosage for them would be they are all around 1 1/2 pounds. I didnt know if there was a chart like bottle feeding where it is by weight or if you just give the same dosage no matter what the size and weight.
