There's Something Wrong with the Cats (Mousebane & Red Mist #1)

Curiosity didn’t kill the cat, it mutated it into a vigilante crime fighter.

Dan's cats are acting weird. One has grown into a strength powerhouse, the other wants to communicate... verbally. And now other kitties have begun to go missing from his quiet suburban street. Could the man in the parka that haunts a nearby industrial estate have answers? Or perhaps it’s something to do with the strange disappearing woman in the woods? Can our hero figure out the conspiracy before it turns into a catastrophe?
