MadCatz mice are multi function gaming mice. Linux treats them as both a mouse and a joystick. Side note, Windows only sees them as mice. Unfortunately, while SDL1 detects the joystick part, SDL2 does not.

src/joystick/linux/SDL_sysjoystick.c:367 has
/* !!! FIXME: only finds sticks if they're called /dev/input/event[0..31] */

It looks like the mouse is reported as an event and mouse, while the joystick is just reported as js0.

Ryan, weren't we going to resurrect the js0 code?

You can set the hint SDL_HINT_LINUX_JOYSTICK_CLASSIC to enable the classic /dev/input/js* joysticks as of 1c78b08
