Boos Hip Bone surgery!

Help my 2 year old kitty Mr. Boo get hip bone surgery ! He is in so much pain that he can barely walk. We carry him around like a baby to get him where he needs to go. Before this he would always play with his brother,sister and mom ! He misses being able to go outside and run,climb, explore,and brawl his siblings in the backyard. The doctor confirmed it was hipbone dysplasia and that he will need surgery. They gave him pain reliever and steroid shots that latsted 2 weeks. Now that the medicine is worn off, his mobility worsened drastically in a matter of days!! I’m scared that if wait to long to get him surgery that he is going to suffer in pain!! The surgical procedure that he needs is (FOH) Femoral Head Osteotomy. An FHO restores mobility to the hip by removing the head of the femur. They remove the ball of the ball-and-socket joint, leaving just an empty socket. scar tissue will form inside providing cushioning,resorting pain free mobility.
