Cat and Mice

Person A: (talking about network data cables) The largest danger to
cable longevity remains mice...
Person B: Any category of "cat" can certainly help with that...

(Cat 3, Cat-5, Cat-5e, Cat-6, Cat-6a ... are all types of network
cables- the one you plug into your laptop / router is generally Cat-5)
