Which of the following is a typical characteristic of the rhabditiform larvae observed in the kitten's feces?

The rhabditiform larvae, commonly found in the feces of kittens, are characterized by a distinctive tail end that sets them apart from larvae of other nematodes. This feature is crucial for identifying the larvae during microscopic examination, as it provides a clear morphological marker. The shape and structure of the tail can be indicative of the specific type of nematode present, which is important for accurate diagnosis and treatment.

While other characteristics such as body shape and the presence of an esophageal bulb may be relevant to the identification of different types of larvae, they do not specifically highlight the unique tail morphology that is emblematic of rhabditiform larvae. Hence, recognizing the distinctive tail end is essential for anyone studying or working with parasitic infections in companion animals, particularly in diagnosing infections in kittens.
