I enjoyed the game a lot!
It was polished pretty well for a game made in a week, and I finished the game until the very end.
If you ever want to continue its development after the jam, I would recommend adding a grid pattern for placing the stations, the ability to remove a station but at the cost of not getting any of the money(sweets) you spent to buy it back, having the stations be upgraded instead of more cats, and maybe have the player a bit more involved with everything so it's not putting something down and just waiting for it to help you reach a milestone to do something else...
overall, I gave relatively high ratings in all criterias since it's pretty well done!
