The Toffees were left frustrated after Saturday's goalless draw with Wolves, but Cahill remains focused and is hoping they can heap more woe on West Ham at the weekend.
Cahill told the club's website: "We don't really look at the league and whether we can still finish above Liverpool. For us, we're on everyone's heels and teams playing us are aware of what we bring. I don't worry about Liverpool, what we're doing is the thing to concentrate on. We've got a big game against West Ham coming up, probably one of the biggest of the season.
"We know how important it is. We want to exploit their poor form and not kick-start their season again. We want to try and do something special at the end of the season."
Despite dominating the game at Molineux, Everton couldn't make the breakthrough and Cahill is calling for a ruthless streak.
"Me, Louis, all of us had chances," said Cahill. "It was just a disappointing finishing display from us, but the run goes on and that's the most important thing. We didn't lose.
"We've come away and kept a clean sheet, but the disappointing thing is we didn't do enough up front.
"Every game is going to be tough. If you look at the run-in there are no easy games. I'd played at Molineux years and years ago with Milwall, so I knew how tough it was going to be."
