Help Leo with his surgery

Hi everyone! My friend Katie’s cat Leo has recently had a lot of health issues involving his urine and bladder. Unfortunately the only thing to help him is a surgery. Katie has already had to spend thousands of dollars and this surgery is going to cost several thousand more. She is a college student and is really struggling. Leo is a really special cat-one of the sweetest, kindest, friendliest cats you could ever meet. Anyone who has pets can understand the bond that Katie and Leo have. Please help them out and donate ANYTHING that you can. Thank you so much.
