I put out cat food outside the trap that disappeared, but haven't been able to catch said predator inside the trap using several baits including the same catfood that it seems to like. The last bird I lost disappeared leaving only a pile of feathers. Conclusions are either the pred is trap savvy or possibly too large for the raccoon trap. I thought I saw a fox run across the road in the dark last night though, so my gut says this was a fox that is too smart to get trapped. Ideas please??
