Item 1.		Security and Issuer
This Amendment No. 4 to Schedule 13D on the Common Stock of  Oil-
Dri Corporation of America  (the "Issuer") is being filed on behalf of the
undersigned to amend the Schedule 13D, as amended (the "Schedule 13D") which
was originally filed on November 22, 2000.  Unless otherwise indicated, all
capitalized terms used herein but not defined herein shall have the same
meanings as set forth in the Schedule 13D.

Item 2.		Identity and Background
		This statement is being filed by Mario J. Gabelli ("Mario
Gabelli"), Marc J. Gabelli ("Marc Gabelli") and various entities which either
one directly or indirectly controls or for which either one acts as chief
investment officer.  Many of these entities engage in various aspects of the
securities business, including as investment adviser to various institutional
and individual clients, including registered investment companies and pension
plans, and as general partner of various private investment partnerships.
Certain of these entities may also make investments for their own accounts.
		The foregoing persons in the aggregate often own beneficially more
than 5% of a class of a particular issuer.  Although several of the foregoing
persons are treated as institutional investors for purposes of reporting their
beneficial ownership on the short-form Schedule13G, the holdings of those who
do not qualify as institutional investors may exceed the 1% threshold presented
for filing on Schedule 13G or implementation of their investment philosophy may
from time to time require action which could be viewed as not completely
passive.  In order to avoid any question as to whether their beneficial
ownership is being reported on the proper form and in order to provide greater
investment flexibility and administrative uniformity, these persons have
decided to file their beneficial ownership reports on the more detailed
Schedule 13D form rather than on the short-form Schedule 13G and thereby to
provide more expansive disclosure than may be necessary.
		(a), (b) and (c) - This statement is being filed by one or more of
the following persons: Gabelli Group Capital Partners, Inc. ("Gabelli
Partners"), Gabelli Asset Management Inc. ("GAMI"), Gabelli Funds, LLC
