I sleep for many hours every day.

An everyday activitiy of mine is sleeping. I’m a cat.

See the difference? “Everyday” means it’s a normal activity or use. The guy I live with has dishes for everyday use, and he has some things he only uses on special occasions. He says he does that because he’s afraid I might break his nice things.

I’m happy with my everyday cat bowls and I’m happy to use them every day.

Remember, it’s “every day” not “every days”.
