Oreo the abused Cat

Oreo is one of many stay cats I feed daily at Sheraton Petaling Jaya Hotel where I work. Sunday when I went to feed, Oreo didn't respond to my call which was odd because he always comes right away. When he didn't show I went looking for him. I found him unable to move and covered in blood. Oreo suffered a broken jaw, severe head trauma and damage to his left eye. The Dr believes his injuries were consistent of abuse,
most likely from a baseball bat or something similar. His medical expenses as of today total $1400.00 If he can not eat or drink then he will need jaw surgery which will cost an additional $1,900.00. Any help you can provide will be greatly appreciated.
