Help save Kiya the sick cat please.

URGENT HELP NEEDED ! Kiya was adopted from me 2 years ago and now she’s very sick ! 
I just received this message and I need help ! 
Please! 

Kiya has been pretty sick for a couple months now. I've been to my vet 3 times so far, and really can't afford to keep doing lots of tests. Right at the moment, all we know is that she is hypercalcemic. She does not have any tumors or cancer that they can find, but the calcium needs to come down before it effects the other parts of her body (like kidney stones which I can't afford to have operated on).

I am not sure if there is any help you could provide , but I am desperately trying to survive on only $500/month for disability which covers practically none of my bills so debt has already been piling up. Of course my babies are a priority and I will always take care of them before anything else, but this is really, really difficult... I've been panicking almost every day.

I am so glad I got Kiya from Destiny's Hope. Destiny’s hope  is a truly beautiful organization that I believe in whole-heartedly, and recommend to people looking for kitties all the time. Kiya has been a genuine life saver for me time and time again since I adopted her about 2 years ago. She is such a strong emotional support, and one of the most affectionate furrbabies I've ever had.

In any case, please let me know if you have any ideas or can help or have any recommendations. It's very important to me to help Kiya get well. I don't want you to feel any extra stress or anything - you are doing so much and are such a wonderful person, but I needed to reach out to every option I could think of. Thanks so much 

SHE NEEDS A SPECIALIST ! SHE NEEDS DIAGNOSTICS!
she currently doesn’t have urinary stones and does not have trouble urinating. 
She needs a specialist to do an abdominal ultrasound and  she needs parathyroid hormone tests and an ionized calcium test.  

Please help $5 is all I ask.  
Please. 
Thank you
