Riddy Cat Needs Emergency Surgery

Riddy had an operation in 2006 for urethra stones. This surgery was botched. Because of this, I could never have her "fixed" as there were too many complications and scar tissue. Vets wouldn't touch her. SO- now she needs a full hysterectomy because her entire uterus is infected.
I've had Riddy since high school and she is the momma to all my other animals. Even ONE DOLLAR HELPS. Please share and thank you so much.
