Technically our weekend, since the spouse's days off are mid-week
We took our much-beloved, 12-year-old kitty in to the vet for what we thought was an infected spider bite. Fortunately for us, our vet is sharp as a tack and always looks beyond the obvious.

Unfortunately, her examination proved her suspicion that it wasn't a spider bite but was in fact a tumour. Kitty has a rare cancer with a long-term survival rate of 0% in cats. If we spent a few month's pay on treatments that will make her sick she might get a few extra months, but our vet advised against it (and I didn't want to do that to her in the first place), so that weekend appointment has only cost us about a grand so far in money. In non-currency terms, it's costing us more than I can describe.

.
When I was 15, my cat had a tumour (it was actually MY cat, as opposed to the family's cat). We paid for the extra months, and I still feel like the world's biggest bastard for making Tasha go through that because I was too selfish to deal with losing her. I'm really sorry guys, I know how bad losing a pet that you love is. Good luck.

I really feel for you
Cats are wonderful things, and to lose one is awful.

Did work experience in a vets
and saw a dog like that were the family were paying for medication to give it a few more months. It looked barely alive which
wasn't very nice to see, they had it put down when it got to the point where the dog didn't even respond to anything.
As hard as it is, it's a lot better to let them go than drag things out like that.

I've seen those people
Their pets always look like they'd be holding a sign reading 'Please kill me' if they could. When we got her diagnosis, I knew there was no way I'd let Clare go through anything like that unless it meant saving her life completely -- same as I'd want for me. Instead of surgery and chemo, we're springing for pain medication and fresh seafood.
