Only her bombs should cause that problem and it's only if you cut them too early/with 2c. If you can, cut them lower to the ground so the explosions get absorbed too. Other projectiles should be cut safe.
Also, cat mace isn't an overhead unless she jumps. Block accordingly. Lows/throws lead into bigger damage than the hammer does. You can also Kishuu under the super air version, dunno about ground. (I assume non super version works too, but yeah)
