After being fired, again, for her obsessive-compulsive tendencies related to cleaning, Katerina Pawslowski is on the hunt for a new job. Who knew that having good personal hygiene could be a terminable offense? Maybe keeping half a dozen containers of Clorox wipes always at hand was a bit much... As she's searching through the paper for a job, an ad from Heart's Haven Toys catches her eye. Lab Assistant Wanted: assistance with maintaining and cleaning the general lab area. Cleaning! It said cleaning! What better job for a feline shifter with OCD?

Wilmington Thorpe III has got a problem. He and his partner have been hired by Heart's Haven Toys to create the ultimate catnip. Catnip which would stimulate and arouse the feline shifters of the world. Heart's Haven is looking to monopolize the market on feline sexual aids and this new creation would be the cornerstone of their marketing campaign.

After several unsuccessful attempts, Will decides his problem is the state of his lab. His partner and pack mate, Montgomery, while an amazing chemist, is a slob. Will can't think with all the clutter!

Montgomery Slade loves everything about working for Heart's Haven Toys. He's doing what he enjoys with the man he loves by his side. His life couldn't be better–until formula after formula fails to produce the results they've been looking for, and as a result, Will spends more and more time in the lab staring at test results...and less and less time keeping Monty warm at night.

Of course, everything changes when a certain Kat gets to cleaning...and changes their lives forever.
