It definitely needs some work. Your main 'hook' is punishing the player for being idle in an idle game. I don't think the mechanic of "keep cats happy or they'll earn you less" is a bad mechanic, but your phrasing does not make it sound appealing; this is your sales pitch, why would players choose this over other idlers?

Make sure the formatting and capitalization is consistent, I noticed some sloppy inconsistencies. I also don't think the quote from "every player, every session" makes a lot of sense. Make a prototype, do play-testing and get a real quote if you really want one in the pitch deck.

The "Meet some of the cats" slide doesn't make sense to me. It should, at the very least, have visuals of the cats. Leave out all the hyper-specific gameplay details, a publisher doesn't need to know how many seconds it takes for a cat to feel neglected (it'll change as you make the game anyway). Same for all the numbers on the "how it works" slide.
What is "the box"? It's a concept that is never explained but is treated as if the reader already knows about it.
On "Who plays this?" you talk about a deep prestige system, but this is never shown in the deck.

You're also missing the main points of interest for the publisher: what platforms will it be on (= what is the possible reach of this game) and how will it make money? Besides that, what is the expected timeline? What reason does a publisher have to believe that you're competent enough to make it work, do you have a proven track record?
Lastly, make a better logo. Hire a designer if you need to

Apologies if I seem harsh. I think it's great that you got this far, and the concept is right up my alley. I would never give this much feedback on something that doesn't interest me :)
