How to get through the fifth level of the cat house at home

Open the iron cabinet on the left to get the vacuum cleaner, come to the kitten with the vacuum cleaner, and suck up the paper next to the kitten to get the key to open the iron cabinet on the right from the paper.

You can open the iron cabinet and get a rag, and then use a vacuum cleaner to suck up all the scraps of paper on the ground. Come to the kitchen, turn on the tap, put the rag on it and take a wet rag. Now you can wipe the mirror on the left with a rag and go through customs.
