פירוש על עבודה זרה 32:4

These are the same opinions we saw yesterday. Rabbah b. Ulla says that the mishnah refers to a maimed lion and follows R. Judah who allows selling maimed animals. R. Judah does not allow selling maimed dangerous animals. If it is not dangerous, it may be sold. But other wild animals may not be sold even if they are not dangerous.
Ashi says that lions cannot perform work in any case. Therefore, they cannot be sold if they are dangerous. But animals that could possibly be put to work may be sold.
