Re: Kitten only gained 2.8 grams in 24 hours ... Please reply
You should be ok. My kittens grew in spurts. If I may ask, do you weigh them prior to feedings or after? If it is after, you are not getting a 100% accurate idea of growth because one kitten could take in more milk one day as well as compared to the littermates.
What kind of scale are you using? Also, how is his suckling? Is he nursing well enough and do you know if momma cat is producing enough milk and/or not rejecting Eli? If you are concerned, feed him some of the KMR as a supplement to mother's milk. You may even want to start tonight just to be safe.
