A total of 2758 Legs.

Breakdown -

7 women - 14 legs.
49 purses with 7 rats in each = 343 Legs
7 baby rats for 343 big rats = 2401 Legs.

Add together = 2758.


Note - If this is crazy and the answer is something like "i never said the purses were in the room".... then you never said they werent either! With the info available, this answer is correct???
