We have just found out that one of the landowners that I shoot for has a bit of a rat problem developing. We have noticed well used rat runs coming from under the back of her poultry house. We can not use the usual rat cage traps (The ones with spring operated doors) as her cat gets itself caught in them (I found that out when we had a mink up there which I ended up shooting) and because the poultry has access to the area poison bait is not much of a practical solution.
I was thinking about the older type of "funnel trap" - The type where the rats could get in through the funnel but could not get back out and the size of the funnel would not let her cat get caught in it.
As both myself and the landowner are against the use of poisons (Unless there is really no other alternative) are there any other suggestions that might help to minimise/clear the rats, or does anyone in the East Lancs Area have a few of the funnel type traps that I could borrow for a little while.
