I took in a couple of kittens on Monday night. they are about 4 - 6 weeks old based on size. they are eating on their own and I have been feeding wet food and KMR. They are rather small about 0.75 lbs. It is a long story, but basicly a feral group of cats was spayed, neutered and moved from an unsafe location to a farm that was looking for cats. The people that moved the group thought all of the kittens had already passed away, but then these two appeared. So I agreed to take them to socialize them. The only issue I am having is that they have fleas. I have treated them with Capstar (1/2 a pill each per the vet), but the fleas must not have been old enough for the cap star to work becuase they are still all over the poor babies. I have bathed them twice. I'm just wondering if there is somethign natural that would be safe for kittens that young? They are skinny and were dehydrated as well so I am trying to get them fixed up before treating them with a stronger product.
