Kitty Vet Visits (FLUTD)

Hi, everyone!

My name is Amanda, and I am obsessed with my cat, Twili. I've had her since she was a baby, and she is now 3 years old. 

Twili was born with two siblings to a stray cat brought to a vetrinary office near my home. The mother was found by a passer-by who noticed she was incredibly ill--upon bringing her to the vet, it was discovered that she had a ruptured mammary gland AND was pregnant.
The litter was born at the office, and the woman who had initially brought in the mother adopted her but would not take the kittens. It was up to the office to hand raise the kittens, since the mother was unable to feed them or care for them post-treatment.
Twili's siblings were adopted out quickly, but there seemed to be something keeping potential homes from selecting her.
And that's where I came in.
My best friend, who worked at the clinic brought me to visit her and it was love at first sight. She has been my side-kick, my head-warmer, and my shadow ever since I brought her home. She is a true delight, the best thing about my day. I love her so much.

However! 
Twili has been battling what the vet originally thought was Feline idiopathic cystitis (FIC), but due to the short periods between flare ups, we're now thing it's Feline lower urinary tract disease (FLUTD) or possibly stones in her bladder. I just had to take her and drop her off again for another round of tests and sonograms to try and narrow it down.

But, here is my problem...
I recently finished school earlier this year, and while I do work, I am swamped with debt and school loans from furthering my education. I hate to see my baby suffer, and I am doing all that I can... but it isn't easy. I don't know how I'm going to pay for her visit today. 

The bills are adding up. 
Please, if you can spare it, help me afford to make my baby healthy. Any amount will help and it will be greatly appreciate.
