cats are purely entertainment animals
even just idly petting one while you fall asleep?
or glancing over and seeing them standing/sitting/lying/walking there and you let your gaze linger for longer than a standard glance?
that's technically entertainment
dogs can also be an entertainment animal, but their entire purpose is to be a working animal, either through herding, guarding, attacking, sniffing, ect.
cats used to also be a working animal, but over time they became an animal who you solely seek out to just "have", to be entertained by, with no other expectations upon them aside from them just being "a cat"
