Most outdoor shotgun mics I've seen have a nice furry wind screen affectionately known (in en-gb at least) as a "dead rat". Most indoor shotgun mics I've seen also have a double life as outdoor shotgun mics, and therefore come inside a 'dead rat'.

My cat will investigate anything pointed at him, and I'm pretty sure would love to see how dead the dead rat really is...

Rather than taking aim at the sampling rate, if anything I'd be more interested in being sure that they'd sampled up to the end of the frequency spectrum that cats can actually hear -- for birds at least the >30kHz part is important.
