Normally, kittens will have a couple of firm, yellowish stools per day if they are being properly fed. Also after each feeding, you will need to gently massage and stimulate the anal and genital area with a sterile cotton ball or piece of gauze dipped in warm water. This will cause the kitten to urinate and have bowel movements, and it is very important that you continue to do this for the kitten until he/she is definitely using the litterbox on his/her own, even though most kittens can control their own bowel movements at about 10 days old.
The skin area is very delicate and may become raw or sore from your efforts. If this happens, apply a tiny dab of Preparation H ointment to the affected area after each stimulation. Keep in mind that your kitten will probably not have a bowel movement every feeding, and sometimes even skip a day. This should be fine as long as the kitten is growing, eating well, not showing any signs of distress, and urinating.
Young kittens must be protected from disease!! ALWAYS wash your hands before and after handling the kittens, and ALWAYS clean and sterilize your bottles, nipples, brushes, or tube feeders in boiling water after each use!! If your kittens did not receive their mother’s colostrum (the watery milk the queen produces in the first couple of days after giving birth), your kittens are at an even higher risk as they did not receive the antibodies present in the colostrum. In that case, be sure to keep them separated from any other animals, also.
