PLEASE! Help save my cat’s life

Greetings everyone. My cat was attacked by a pitbull on Thursday afternoon December 8, 2022. My cat wandered onto the stoop of our home and that’s where the attack happened. The pitbull hurt my cat so bad he almost died. The dog caught my cat by his belly. The pitbull bit my cat’s belly puncturing his belly and as well the pit bit his armpit. My cat was shake’n by the pitbull. Someway my cat got away from the dog and walked away disoriented and scared. My cat didn’t come back to our home he went the opposite way and went off into the backyards. Me and my family walked all through the backyards next to our home looking for our cat. No luck on Thursday, Friday. But on Saturday the search was on again. No finding that morning but Saturday night again the search was on and he was found. We got him inside out of the cold. We wiped him down best we could and awaited the morning to come to rush my cat to the Vet. As well he also have a problem going with his liver. Please we are asking everyone to help. I can’t afford to pay for his. We appreciate and thank you in advance
