Cavan are staring at life in Division Three next season after throwing away a chance of taking a second National football league win at Cusack Park in Mullingar.
They shot 18 wides in the entire 70 minutes in a game that saw 11 yellow cards issued by Tryone referee Michael Hughes.
Afterwards Breffni manager Donal Keogan admitted he was disappointed at the way the game panned out after turning round 0-5 apiece at half time.
"I thought at half time we were in control of the game, and we were winning midfield.
"We kicked 10 wides in the first half and our shot selection was very poor. It was the same in the second half and we fizzled out of the game. I was very disappointed with the performance.
"It looks as if we are destined for Division Three.
"We were short a lot of key players but I am not using that as an excuse, because we had enough possession to win the game.
"Michael Ling is out of the game at the moment with a hamstring injury and it will be about another three weeks before he comes back."
Westmeath now have eight points from six games and a win against Monaghan next time out will see them playing for Division Two honours.
Westmeath scorers: D. Dolan 0-3 (2f), D.Glennon 0-3, M.Ennis 0-2, D.Bannon 0-1 F. Wilson 0-1 (1f).
Cavan: D. McCabe 0-2 (2f), R.Flanagan 0-2, M.McKeever 0-1, J Reilly 0-1
