This cat thing dumped herself on our doorstep about 6 months ago.
When she arrived she had a life threatening gash all around her neck that needed 200 euros worth of stitches and treatment.
The vet said it was consistent with a young fox. Apparently the foxes disable cats, small dogs, large rodents etc. just enough to stop them running away, take them back to the family as trophy and 'play' with them until they get bored and just leave them to die.
However mrs cat is not so innocent...she does the same with birds and small rodents...and brings them back here....although she often eats the mice and voles whole including the head and throws it all up in the hallway during the night.....
I hate cats really......
