Help Joy the Cat Get Medical Care

My name is Lindsey and I am raising funds for my friend who is desperately looking to get her cat to the vet but can not afford to. Her 4 year old cat, Joy, is suffering with what we think might be bladder stones and she might need surgery to remove them. She's straining to urinate, has lost her appetite and is clearly in a lot of pain. We need to get her to the vet ASAP but need help to pay for the X-rays, bloodwork, and emergency vet fee. Then, if the vet says she needs surgery, she will need help to cover that as well. Anything you can donate will help tremendously. My friend is a good person who volunteers for animals all of the time. She just doesnt have the income because she is on disability.
