Oreo's Urgent Surgery Before Baby Arrives

Hi, our cat Oreo, aka Big Momma, needs surgery again. This time she has bladder stones. Unfortunately, we do not have the funds to pay for her surgery. We have a baby coming in February. Oreo is only 6 years old. We got her when she was 2 years old, and she is so lovey and cuddly. We would really appreciate it if we could get some help to get her surgery so she is no longer in pain.
