Is cat food good food to use as bait?

Well last was working and I was heading home to check on things when out of no where a brown streak ran out from side of road and I hit it, I figured I just hit a rabbit but I turn around to check and what I find is Weasel, Dead, I have been trying to trap these things and they keep getting away, So one down who knows how many to go, I hit it right near my house.
