I've posted about Wally before, and I've posted on other threads about similar things with my own advice suggesting that 'you'll know when it's time' and that 'if they stop doing the things they love....' its probably time.
But this is very very hard for me to tell with Wally, everything I thought I knew about judging whether it's time to have her put to sleep is out the window. She just keeps going, she's eating and eats all her treats off my finger still, she gets up and down all four floors of their cage though very very slowly and with much difficulty now. I've just rearranged some things and taken some toys out so she can get everywhere more easily.
The thing is, her tumours are so big. I've never seen any like it before, they have almost engulfed her legs and her bum, she has one growing on her throat now and though she eats lots and I've been giving her lots of peanut butter and fatty foods to try keep some weight on her, she is absolutely skeletal. I am devastated because she seems so fine, waddling about, eating, then when I hold her I can feel every bone in her tiny fragile little body. I don't know why she isn't keeping any weight on, but I can only assume more is happening in her little body than I can see on the outside.
It's so hard to see her so thin and fragile, but her tumours, though bigger than I've ever seen on a mouse before, haven't ulcerated yet and she still eats and seems quite....feisty though very fragile.
I know this has been a long post but it's hard to explain without going into detail.
When it's like this, I just don't know what the best thing to do is, I love her so much and I'd rather her go to sleep in her own cage, but tonight, I just couldn't believe how thin she felt. It was truly heartbreaking. Just not sure what to do.
