My kitten’s eyes are discharging pus and it can’t keep them open. What eye drop should I use? (First time dealing with this; the kitten has no other symptoms.)

Eye discharge with pus in a kitten is usually a bacterial eye infection or bacterial conjunctivitis, caused by contagion, overlong eyelashes, injury, or bacteria. Clean the eyes with a gentle saline solution, then apply a vet-recommended pet eye drop several times a day.
