One of my cats is coughing away and so I ahve been giving them lysine so she will get better and so the others don't get it but I need to know if it is ok to give my nursing mom lysine too? The kittens are large 3 out of 4 are over a pound but they look young like three weeks blue eyes and rounded ears. They are using the litter box now. i just wondered if you can give a nursing mom lysine...
