Thanks for playing the game and finding the cat :) There is no special dialogue for finding it, because of the one special dialogue(one dialogue triggered by variable) limit. I wanted the female scientist to thank you for finding it, but it is what it is...
The other item in the closet was supposed to be a bucket(reskinned armor). Not my best job.
BTW I've updated my game from the previous jam with some of the new mechanics, so if you decide to revisit it at some point you'll probably like the results.
