I killled a mouse

I actually love mice obviously not in my house but I think they are dear little things I did kill one completely by accident and it upset me so much.
It’s the only time I ve had a mouse in the house and I knew I had one and had been trying to lure it out. One night, as I was sitting watching TV, I suddenly saw it out the corner of my eye scurrying towards the door, I reached over and shoved the door to stop it escaping to the rest of the house, then I could contain it in one room catch it and put it outside, Much to my horror as I shoved the door shut, that was the very second it was escaping through the door which hit it hard and killed it instantly. I was so upset I was crying and kept imagining it had a little family waiting to be fed. It really did upset me a lot

The animal suffers terribly. Please don’t use poison.

We once found two dead rats on our drive that looked like someone had poisoned them. There are cats, foxes, sparrow hawks, owls and red kites round here that could all have eaten them.

I once killed a mouse inadvertently by shutting it in a bedroom that we rarely used to go in. I went in one day and the room smelled bad but I couldn't work out what the smell was. As soon as I had a day off work I ransacked the room, cleaning every inch of every drawer, shelf and cupboard. There was only the floor left to hoover and as I closed the wardrobe doors I found a very flat mouse under them. It looked like Jerry after Tom had flattened him with a hammer, arms and legs sticking out. Very sad but we were totally unaware it was in there.

I don't kill mice if the cat brings in live ones. I have humane mouse traps. I take them and release them as far from the house as possible.
I dislike poison. I once read about a family of owls killed by poisoned rodents.
