My baby cat has to have surgery on his bladder

My little boy had a urinary blockage a few months back and I was able to come up with the funds for that but now it’s happened again and he’s in another ER who’s prices are more expensive and now he needs more medicine, another catheter, and surgery to hopefully help prevent this from happening again. He is only 4 years old and is a very loving mamas boy who would be dearly missed if something were to go wrong. I’ve not done something like this before but i’m not able to come up with the funds by working full time and even asking family for help. Anything would be absolutely amazing. Thank you
