Real Life Case: Mammary Tumour in an Old Doe
Sufferer: Whiskas, 20 months, doe.

This tumour appeared overnight and was a bit of a shock. Whiskas was an old mouse, but a real trooper and still very active. With other health problems to worry about, we had been informed that she could not be operated on and survive. This meant that we only had the choice of whether to put her to sleep or not.

I decided to let her go on for a while until the tumour began to affect her. In the beginning it really was the case that she didn’t notice it and behaved perfectly normally, not even slowing down. The tumour stayed the same size for a week or two and then suddenly increased quite dramatically in size. For a start it was just Whiskas’ walking that was affected, as the tumour was now between her front legs too and she began to waddle a little.

As the days went by, she slowed down a little – but still proceeded to climb up both my arm and the toys, managing feats that some of the young healthy mice could not. However, we began to notice that she was gradually declining with the tumour’s progress and I knew that the time had come for her to be put to sleep peacefully, before she began to suffer. We took her to the vet’s soon afterwards. It was very peaceful and very sad, but we knew we had done the right thing for her. To let her go on in pain would not have been fair, especially when there were no possible good outcomes left.
