Still no luck finding a cage trap, but I should be able to get one next time I go over to Sarf Lun'non. Interesting that they should be available in a conurbation, but not out here in the semi-sticks. No pets in my garden - I seem to have succeeded in keeping the cats out - which may explain something! But there are other things around that I don't want to kill.

It's a brown rat, but not at it's biggest (classically described as "as big as cats")

Today I search for an agricultural supplier.
