I think kittens and cats should be restrained very very good
but i think there should be comfortable clothes for the cat so I think the following things should be there when you are a cat / a kitten
*plush, very thick, mittens that go to the ellbow and that you cannot grab with your hand for things (I hope you can understand me, I am from germany and I cannot speak very good english) So that you can't use your hands. Maybe the fingers should be bent so that is a real cat-feeling, but this is not necessary because it can cause pain. They chouldn't be opened so they culd wear a padlock so you can't open them *a very thick costume that is made from plush and is closed by a zipper in the back, closable by a padlock. It should have opens for the ass and the pussy so you are able to pee and poo while you are a petty... but the ass must be closed with an buttplug with a tail on *a mask that looks like a pet (cat or kitten) that you can regulate the fresh air and the look, that means that you put an eyemask over the eyes so your small kitten cannot see anything *collar *the hands and the feet should be tied *the cat shouldn't be able to stand up so it is necessary to do something for that
