We claim the ornamental design for a shower caddy, as shown and described.
FIG. 1 is a front elevational view of a first embodiment of the shower caddy; and,
FIG. 2 is a rear elevational view thereof.
The broken lines representing the hanger and the vertical pieces connecting the caddy to the hanger form no part of the claimed design. The other broken lines and zig-zag lines represent stitching, which form no part of the claimed design.
