My rabbit, last night, did not poop at all, i gave him a slice of apple and massaged his stomach and a baby carrot, then he was fine and started pooping like normal. Now tonight, he's not popping again, but he's eating and drinking like normal. But not pooping for this long is not normal for him, its been about 5 hours. ( he isn't eating the poop, so it's not that) Is this normal? And will he be okay? What should I do?
