Need some advice from someone. My 7 months old kitten has had bad eyes for a while now. Took him vets and they gave eye drops. Put them in and it's not so greedy colour and it's not running now but in the photo above he has dry crust at the top off hiss eye lid. The worse off his eye infection has gone he did also have mild cat flu. Can anyone help is there something I can buy as it's got to be uncomfortable for him. Thanks in advance
