Idk how different cat hair is from dog hair, but we have a Rottweiler and a German shepherd husky mix, and we vacuum daily. We have a Roomba that we don’t really use anymore, but it filled up daily with dog hair. Very little loose hair in the house now.
I thought I saw or read that their special forces were using snorkels to sneak in the water. I know that doesn’t answer your question, but I wanted to pile on a little.
