These aren't equivalent. The first implies the existence of the
package "menagerie.cat.models" while the second implies the existence
of "menagerie.models.cat".

Generally, no. It can be convenient for use in the interactive

you use it in real work, then you end up in situations where you can't
tell just from looking at the source what names are actually being
imported.
