When assessing whether or not you have a sick kitten or sick puppy, it is always best to err on the side of caution. In evaluating the health status of a puppy or kitten, some things to consider:Attitude
Is your puppy/kitten bright and alert? Does he appear active and playful or dull and depressed? Signs of potential illness could include excessive sleeping and/or no desire for activity. The ears should be erect and bright and a wagging tail is always a positive sign he feels good.
