Sounds a bit like Bookshop and Bonedust , a cozy adventure story in a seaside town, set mostly in a rundown bookstore whose proprietor is a mouse person.
An even closer match: The Village Library Demon Hunting Society by CM Waggoner.
Minus the edit that turned "cat" into "dog".
That does sound very similar!
