My cat brought in a baby bunny HELP

Vancouver WA

Description

My cat got out and there were 2 baby bunnies in the hallway this morning. 1 was already dead but one looks OK ish. I know that once a cat gets them there is usually nothing you can do so I am trying to not let my expectations get away from me. At the same time I have bottle fed cats and birds so it's not completely unfamiliar territory. I thought about trying to find someone with rabbit that has babies but with him being wild idk I will try to find a local rescue but how long can he go without food and water? I have water in with him and tried a dropper just for a minute but he is too scared at the moment. It's only been like 2 hours. Any help would be greatly appreciated.
