Although this just looks like a regular mouse, this patient is actually the first of the year for us. This is a yellow-necked field mouse. The yellow-necked field mouse looks extremely similar to the common field mouse. These mice look so similar they were only identified as separate species in 1834! The way to distinguish them is by size and colour, with the yellow-necked field mouse being slightly larger and lighter in colour.
This mouse was brought into the hospital on the 30th of November 2025 due to a cat attack. He suffered a large wound on his back, mainly affecting the right flank and right back leg.
Although his back leg was damaged, he was still mobile on all four legs, however, was very stressed and alert.
Our vet, Judith, got to work performing surgery to stitch up the wound. It was a successful surgery, and our yellow-necked field mouse looked a lot better. Post surgery, debriding will be needed to remove damaged tissue and promote healing.
Currently, our patient is at the hospital being monitored and cared for. We wish him all the best in his recovery and cannot wait to see him back in the wild.
Please help us protect British wildlife by taking steps to reduce incidents like this. Studies show that using bright collars with auditory cues such as bells significantly reduce a cat’s chance at hunting success, therefore helping to protect mice and other wildlife.
