Watford and Wolves have been scrapping over seventh spot for most of the season, with the Hornets winning 2-0 at Molineux in October.
But Cathcart told The Sun: “Wolves get a lot of the credit and rightly so.
“They have just come up and pushed into the top of the league and deserve the attention. We have taken a sort of back step and have been quieter.
“I think people see it as a 50-50 game. We know it will be really tough and have seen how well they have done. We are sort of neck and neck in the league."
Since then, they have lost FOUR semi-finals, most recently 2-1 to Crystal Palace in 2016.
"A few of us have been there before and maybe we will handle the pressure better to give us an edge. I remember our semi-final was not a very good game.
“It was a disappointing day but a good experience to play there.
“It was my first actual game at Wembley as I had only been on the bench for a play-off final with Blackpool."
