My cat just fell out the window...

Yes VeeVee, thanks for the lesson in straight talking. Five days ago when I had to make this very decision I knew that I was telling the vet that, yes, I agreed with her decision to kill my beloved cat. If I want to say she was put to sleep or put down then I don't bloody well need someone who believes in fucking reincarnation telling me I am being silly.
It wasn't a choice, by the way: she had a tumour the size of an orange inside her. I could have taken her back home where she would have continued to be in discomfort (or maybe that is another euphemism of which you would disapprove) and be unable to eat, as she had been for the previous couple of days. I could have let her die a 'natural' death when she was 'ready'. And maybe in her next life she would have come back as a vet so she could tell me what a deluded and selfish bastard I was for making her suffer a little longer than she had to.

Do you know what the tumour was?

Found out one of my cats has lymphoma yesterday. She's not eating very much (almost nothing, until today, where she's done a great job of eating most of her regular breakfast - although I put the cat food right next to where she's resting). She's been losing a lot of weight over the last month or two, and 0.2kgs in 3 weeks or so. You can feel her spine in a way you couldn't before when petting her. For a month, possibly longer, she's been putting herself under blankets, behind couches, in boxes (well, she always loved to be in boxes), and just resting/sleeping. She's clearly does not have much energy and is a bit more clumsy in her movements.

The options are pretty lame. Chemo to add 4-6 months, some drug cocktail to add 4-6 weeks, or let her go. Reading about it online, life expectancy is 4-6 weeks from diagnosis. The vet didn't notice the tumour when I brought her in 3 weeks ago, but did yesterday - and he said it's quite advanced. I have no idea where this leaves us and her in terms of time.

Not at all sure what to do. I don't think she's suffering (the vet said it's not a particularly uncomfortable sickness), but is certainly not living the fullest of lives right now. Fucking sucks ass.
