Three abandoned  kittens in my backyard around one of my
storehouses---they look to be about two weeks old (?).

I started hand feeding them the other day using PetAg KMR milk in a
nursing bottle with a queen's nipple; also, I feed them a little beef
baby food.

I just realized that one of the kittens has a heavy infestation of
worms--definitely not tape worms. (Also, two of them have crusty
formations around the eyes, closing one. And they have fleas.  Overall
I'd say these kittens are a little unhealthy and certainly
undernourished.)

These worms are about 1/3 of an inch in length, white, round, fat, and
tapering to a small black head.  They are all about the same length &
size and are very active.  I pressed both around the anus and penis area
and the worms started oozing out; I was able, with a pair of tweezers,
to remove about 10.  Are these roundworms?

I keep these poor kittens outside under a porch--in a box with plenty of
fresh paper. I don't want them indoors at all--I have four healthy
indoor cats, and I can't risk giving them a disease.

I would appreciate your opinion.

The good thing about all of this is that the little kittens love me for
feeding them; I'm their second mother!  Poor things--I feel sorry for
them, but I'm afraid their future looks a little dim.  I guess I'll turn
them over to the SPCA or the Humane Society in the next day or two.  A
veterinarian?  No.  I spend enough money as it is on my indoor cats.
