As for putting cats into vacuum bags to drain out the air, this is a very inhumane practice and can cause the cat to suffocate. Cats, like us humans, also need to breathe oxygen, and the cat's breath holding time is not long. If the cat is put into a vacuum bag to drain the air, then after a while, the cat will suffocate due to lack of oxygen.
In addition, cats are very cute animals and are usually quite clingy to their owners. The cat is loyal and will become more dependent on its owner as long as the owner spends some time playing with it every day.
