I love cats, and I found this game quite cute! It seemed to flow along easily for me. The lack of art or photos was, in my mind, not a big loss, as my imagination filled in the blanks. I liked the rainbow text and Italian lessons too. The game is short and simple, and definitely suitable for children.
Most of the games in this jam had tutorial messages during the gameplay, but I think yours only had explanation in the intro. So you could expand it to the game itself so it is even more accessible to total beginners (play Excalibur and examine its code for examples of how this can be done).
I think you break unwritten text adventure conventions, like forcing the player to examine things in a certain order, or offering multiple options (chicken and tuna). It was fine in my playthrough experience, but can cause frustrations for others. Usually if someone examines something, they don't expect the message to change if they examine it again under different conditions.
A small thing I noticed: after I already found the key and unlocked the door, when I examined the door again it still said it was locked. Check for things like this if you want to get the game extra polished.
