We couldn't afford to keep giving the kitten formula to a little 3-week-old drop off my dd found in the woods (Raiden, above). I'm glad
Wal-Mart sells it for only about $3.50 a can (as opposed to the first can at $7 I bought at the pet shop) but it was still too much for us at that time.
I called the vet and they said to make the following mixture:
1 can evaporated milk
1 can (refill same amount) of water
1 egg yolk
1 tablespoon honey
I did buy some cat vitamins from our store, and crushed them up and added them. He LOVED that mixture, and did very well on it.
Later, I added it to soft bread, or kitten food, and also added leftover meat and sometimes canned tuna.
I wish I'd seen your post earlier. I guess they are about done with the bottle? I found the kitten bottle very difficult to use, and he never liked it much. A small syringe worked much better. I could control the flow rate better and it didn't frustrate him as much. But by now I suspect they are about ready to start lapping, and you said one was?
So sorry to hear about the one that died. I hope they don't have anything that can endanger your other cats. I agree with the post that said a good pic and a sad story are the best way to find new homes. You could also try craigslist or freecycle, but kittens usually go slowly on those.
Good luck with the little ones, and I'm glad you took the time and made the effort to save them. I can't let any little ones just die either (which is why we now have a second cat!) ... I hope you find good homes for them.
