Most of my cats have adored them, when they were able to see them instead of just being subjected to the noise. I can't imagine how wild the experience must be for a creature with only the barest capacity for abstract conceptualization. The great grand-pappy of all laser pointers has shown up, and the humans are fighting him? It's absolute horror movie shit when they couldn't see them, though.

Dogs, they've all hated them. Even my deaf pupper Godog was real wary of whatever the hell was going on out there.

(Edit: I mentioned this to my sister and she's reminded me that phoebe and godog both were absolutely mad for daytime fireworks, even once knocking out a window so they could go catch one of the smoke parachutes that was drifting down the beach. I think it was that all the kids were out there clearly having fun with the daytime ones - they were always game for groups of small humans doing anything and would get caught up in the excitement of any event. I now fondly remember one of them getting ahold of a large smoke canister during a photoshoot and leading us all on a merry chase, damned chaos gremlins. I miss them.)

My parent's cat turns into a pitiful mess during new year's eve.
