A very easy, very safe way to kill fleas on ANY AGE of kitten is
food-grade DIATOMACEOUS EARTH. Garden & feed stores sometimes carry it. You'd only need maybe 3 oz, & it'd probly cost $5-13 for 1 lb. (That's usually the smallest size you can find). D.E. is a powder that feels like baby powder that you would just sprinkle on the kittens and gently rub all over them.
Be sure to get FOOD-GRADE D.E. It is all-natural & kills pretty much ALL INSECTS with which it comes into contact (You can use it to get rid of mites & lice on chickens, too). It scratches the skin & exoskeletons of insects & causes them to dehydrate & die. However, D.E. feels soft to human & animal skin--it only really scratches extremely tiny critters.
If you can't find any D.E. locally, email me your mailing address & I can mail you enough to treat your kitties for free. However, it might not get there in time since no mail goes out tomorrow 'cause it's Memorial Day, & I'd be sending from Utah & it could take a number of days in the mail.
----------------------------------------
To keep the kitties warm easily, you can hang a heat lamp (like you use for baby chicks) or just a regular shop light (Sold at
Wal-Mart for about $5) a few inches above them with just a normal 60-watt light bulb in it. Be sure to securely attach the lamp to something solid so it can't fall down or get tipped over. Using string to secure it well to a sturdy chair can work well. Be sure the light is not too close to something flammable.

To clear up pink-eye in cats, you can use Neosporin or a generic triple antibiotic ointment (These are sold in grocery stores or
Wal-Mart for $2-6). (Be sure to get one that DOES NOT say "With Pain Relief" in the name). There is a post about how to use it at
