What characteristic is associated with a rabbit that is described as "meaty"?

A rabbit described as "meaty" refers to its body composition, specifically its ability to carry a large proportion of muscle and meat relative to its size. This indicates that the rabbit has a well-developed body structure, which is desirable in certain contexts, particularly in meat production. A meaty rabbit will typically have a broad back and a full body shape, allowing for greater yield when processed for meat.

In contrast, a rabbit with a small frame, a long, slender body, or a slender neck would not exhibit the same robust characteristics associated with being meaty. These traits would instead suggest a rabbit that is less substantial in terms of meat yield, which goes against the definition of what makes a rabbit "meaty." Thus, the characteristic of carrying a large proportion of meat for its size rightly aligns with the description offered in the question.
