I most fondly remember how delighted child NPC are by the summoned cat (and by Boo) and follow it around. Not entirely useful, but very cute.
True, I do like the reactivity of NPCs to summoned familiars, even if it's a bit wobbly. Though I didn't see anything like the issues it caused in early access in the full playthrough, just the odd cosmetic niggle (eg Doni, who can't speak, eg, still had a line popping above his head commenting on my raven familiar). In early access it was possible to distract NPCs with your familiar to enable you to sneak past them, though as I wasn't playing a sneaky character this time I didn't try to see if that's still possible even though reactivity seems to have been toned down. But I'm with you that it's cute enough to be worth it anyway, even if it doesn't always work perfectly!
