Brennan owns several cat but one cat in particular, named Lazuli, liked sitting in the bathroom sink. For some odd reason, many cats like sinks because of the shape and cool surface.
After pricing sinks at Home Depot, Brennan realized he could get a cheap one for about the same price as a cat post, so he bought a sink just for Lazuli. Now Lazuli has a sink to lounge in all to itself. Even better, the other cats don’t share Lazuli’s love of sinks so Lazuli has his own private sink separate from the bathroom that everyone else uses.
