Help Kelsey Save Her Cat

This is Kelsey’s cat Ryder, he recently became very sick with a Calculus ("stone") it needs to be removed from his bladder. When a cat has a urinary obstruction then they require emergency treatment. Sedation or general anesthesia will be needed. He is in a lot of pain and is going under for surgery. Unfortunately it is very expensive. Kelsey is a full time student and works as much as she can, her cats are her babies. Please help her be able to treat and cure her baby boy Ryder. It is greatly appreciated.
