<human>: So first, a little background: She's almost 6 years old now, and has never really gotten along with anyone/anything. Typically, however, she just minds her own business. We got another cat about 1 year ago, and while they don't necessarily get along, they still keep their distance. We've got a dog now that we've had for 5 months.

Now down to the issue: About 3 weeks ago she started urinating often, and in small quantities, and it contained urine. Worst part was, she started doing it outside of the litter box. We took her to the vet and she was put on antibiotics. 2 weeks later and she's back in because things haven't changed. They ran a full panel on her urine and blood and found that it's not a UTI and pretty much everything looks fine aside from the urine. Now they're recommending an x-ray to look for stones.

Since we can't afford that right now (we've already spent around $450 and that would be another $250), we're waiting until we get our tax returns. In the mean time, she's still having the same exact issue. We've added another litter box (Totaling 2 now), and while she hasn't abandoned the litter box entirely, she's still peeing on the floor.

It's starting to put a strain on mine and my girlfriend's wallets, stress, and emotional state. I love this cat because I've had her so long, but I'm just not sure what to do. Any suggestions would be helpful.

Condense the text into a few key points
<bot>: my cat is pissing blood on my floor and despite vet visits isn't improving. I'm not sure what to do until our next vet exam.
