Let's see what your finished setup looks like. Will there will be a ramp then maybe something bigger on the wood dowel in the middle? Had a mouse get under our boat cover and eat some of my new SeaDek flooring. Caught it but the damage was done so smashed mouse with a cement block and left for the other mice to see. Anxious to see what works as I'm getting ready to winterize/store my boat.We will see if it works?
If not I drilled two hole in a good bucket!
