Please tell me i'm not being cruel. I really love animals but we have this rat in the house. Been here since October and it lives in the loft/the wall cavities. I can hear it all night running around and so far humane things to catch it and release it in a forest have failed. It has recently been coming into the kitchen which I really find disgusting and nicking my dogs biscuits and even fruit from the fruit bowl I have really had enough now and so I have got a big rat trap. Laid it on the rats usual route to the dog biscuits so waiting for a loud snapping noise...am I being cruel?
