How do I tend to a kitten I picked up off the street in poor condition?

Poor eye condition. Won't eat. Trouble breathing.

Take very good care of it take the kitten to the vet tomorrow and have them look at him

keep it warm and make sure its nose or eyes arn't running. give it lots of attention and don't leave it alone for more than a couple hours at a time. gently massaging its chest or back (not the belly!) may help with the breathing. with the eating part... try force-feeding - gently - soft or liquid food, stroking the throat will make it swallow.
