FHO surgery for Tom

Hello, our names are Kitty and Tay. We are cat lovers and rescuers. I, Kitty, found sweet little Tom and his sisters in the woods behind my work and fell in love. One of his sisters was rehomed but the other, sadly, was recently lost to FIP. Less than a week after her death we discovered that our poor Tom is suffering from a rare disease called Legg-Calve-Perthes and it is destroying his femoral head on the left side. Luckily we can get him surgical treatment but it will be expensive. We'll do anything for our babies and are going to save every penny we can to help him but it's a steep goal and we definitely need help. Thank you so much!
