Ok, so my girlfriend has this cat she has had since she was 9, meaning the cat is 17 or 18 years old. Lately, it has been doing some weird shit.

* It doesn't eat much, one or two bites of food
* Low pitched meows in the middle of the night
* Small amounts of urine in odd places (she's never done this before)
* Traces of blood in urine
* Losing weight
* Not comfortable being petted

The final straw as far as I'm concerned was when it pissed on an expensive sweatshirt of mine this morning. This is completely out of character. We have discussed putting the cat to sleep, but naturally this is hard for her. I personally think cats are basically equivalent to goldfish. I suppose they're nice in that they don't give me any shit and don't need much upkeep, but they're not real pets. I am in favor of putting the cat to sleep, not because I dislike cats but because I suspect she's in some kind of pain (although I'm not 100% sure) and because the symptoms are taxing on my girlfriend. Essentially she's watching her beloved cat deteriorate before her eyes. This stress on it's own would be a lot, but we also have a newborn and a 3-year old. So anyway, I just wanted the hivemind's thoughts on this. It occurred to me that my perspective might be skewed because I don't give a shit about the cat itself, only it's effect on her wellbeing. Thoughts?
