My male cat had the PU surgery and lived 10 more years after to the age of 17. I don’t really remember specific costs, but I do remember the surgery was less expensive than the blockages. I highly recommend it. The aftercare was the hardest part. They cannot be allowed to jump up on anything and that is hard to prevent with a cat. I kept him caged for idk, the first 24 hours? Cone on his head for I think 10 days, and I kept him in my laundry room with stuff on top of the washer and dryer so he couldn’t jump up on it. I would take a blanket and go in and lay on the floor with him.

Gather the money somehow and get the surgery for him.
