Curtis...I'm glad to hear you say that you are going to have the kitten tested for feline leukemia. Most vets use a combo test that also tests for FIV (feline aids). Anyway, almost ALL kittens have intestinal parasites. The kitten needs to be dewormed at three weeks of age...and if your kitten's eyes just opened, then he is probably around ten days old. It's rare for them to open their eyes before 10 days. Another good way to estimate their age is by watching for their baby teeth to come in. That typically happens at around three weeks of age.
Kittens get their 1st shots (distemper and another deworming) at 6 weeks old, the 2nd set (same as the first) at 10 weeks old, and their 3rd set (distemper, rabies, and deworming) at 14 weeks. They can usually be tested for feline leukemia after they are six weeks old, but the vaccinations for feline leukemia are typically started at 14 weeks old.
SilverTongue was right about cats being lactose intolerant...dogs are too, by the way. Cats can actually handle milk and fat better than dogs, but that's off the subject

Kitten milk replacer is the best thing to use for your little one. Never use "people" milk.
A warm damp washcloth works best for stimulating the kitten to use the bathroom. This sounds gross...but a washcloth is rough like the mama cat's tongue.
Good luck! It's a lot of work, but also LOTS of fun! By the way, how often are you feeding him? And how long have you had him?
