Cat Pellet Removal and Hip Dislocation Surgery

My cat, named "Wildcat" ironically due to his lethargic character, is a 5-year-old male, white and orange cat, who recently got shot with an air rifle 4 TIMES on his abdomen and chest with an airgun at pont blank distance. Also, the person who shot him did not hesitate to kick him (probably while in shock) on his left rear leg. One of the four pellets landed near the end of his spine while the other is close to one of his kidneys, both being dangerous in case they move around. The kick also dislocated his leg from the hip, resulting in his left foot and tail being completely paralysed. I desperately ask for your help, even if that means the lowest amount possible, because my family cannot afford the surgery cost which is over 500€. We only have 100€ on our disposal (yes we are not the most wealthy, I know ) and the pellets must be removed ASAP because lead is toxicant. I know this might not seem important but we have informed local organisations as well as the authorities in order to arrest this person and rise awareness of these kind of people living among us. Thank you for reading this.
