We have 2 kittens with the ages of 6 & 8 months. The 6 mo. old (Kobe) has been diagnosed with FHV. He has finished his meds but still has the runny eyes. He sneezes occasionally & the cough is gone. I have read on here that so many people have success treating FHV with Lysine. So I bought some this evening. My question is how much do I mix with their wet food since they eat from the same bowl? We've tried feeding them separately but they still end up together. Any advice?
