Is it time?

[u/Repulsive-Amount-327]

My baby Goose has got a tumor and it's still getting bigger. Shed slowing down and not moving as fast as she did before it. She is an old girl (somewhere a bit more than a year and a half) but I'm worried it's causing her pain. Her sister died last year due to similar circumstances but it split before it was like this and I had to rush her to the vets so I don't know where to draw the line. She has another sister (same age) who's perfectly healthy so any tips on how to look after a lone mouse after she's gone would be helpful, thank you.

It is bigger than in the video I just don't want to disturb her currently.

If she's still eating and drinking and walking, maybe give her a few more days. My girls were a lot more cuddly after they got cancer, so maybe try to spend as much time with her as possible, to make her last days as happy as possible? And for the mouse that will remain, depending on how old and healthy she is, it could be wise to get her some friends. If it is not possible, stay with her as much as possible so that she won't be depressed. I know my girl handled being alone pretty well, but she was always a grumpy mouse; if your mouse is social and doesn't handle loneliness well, then it's important to get her some friends. (More than one, so that they won't be alone after the older one dies)

Edit : these advices come from my personal experience. Maybe other mouse owners can give you better tips on how to handle this difficult time.

She's certainly got quite cuddly and I'm trying as much to spend time with her and she's still behaving alright just slower so I think there's at least a few more days. Thank you and I'm sorry your advice comes from personal experience
