I found some abandoned kittens, about 2 days old. I have been feeding them KMR through a bottle. However, their urine smells terribly like fish! Not just a little, a lot! However, the urine is clear, not cloudy. Vet says he doesn't know what is wrong, does anyone out there have any idea. They are too small to feed water to them. Thanks for any info.

I have no idea what would make their urine smell fishy. If the vet doesn't think anything is wrong, just wait and see if it clears up.

The mother could have eaten a lot of fish while pregnant and nursing.

If you plan on continuing the bottle feeding, try a more natural milk that is full of good stuff. The store bought stuff is OK as a emergency, but long term just doesn't have a lot of nutrients in it.

You'll be amazed on how much they will grow on that! The KMR could very well be giving them that strange smell. I had to nurse 3 orphaned newborn puppies over christmas. The store bought milk did them no good. The homemade milk did wonders for them!
