Hello. So sorry to hear that Lily is having this issue.

Prices vary widely from veterinary clinic to veterinary clinic. It also depends on if a board-certified surgeon is doing the surgery or not. A board-certified surgeon will increase the price. Did your vet not give you an estimate of cost?

I suggest you call a few clinics in your area to get quotes. My best guess would be anywhere from $800 to $3,000.

Hope this helps. Best wishes.
