Recently(yesterday) my rabbit, Poe, passed away. I had only been sleeping for about six hours before I woke up to my rabbit kicking his legs repeatedly while laying on his side. I brought him out and tried to get him back to his senses but then he twitched a few times before dying in my arms. He was very healthy that morning before I slept, eating and hopping around. But he did like to chew on things a lot, like cords and once ate most of my flip flop. I cleaned his cage when was needed and fed and gave him water on time.
I have had two rabbits before but the first died from his stomach lining exploding after surgery, and the second was because he was just sick. We never really found out about him.
Please help or give an idea to what you think was wrong. I only had him for about 6 weeks since I received him from a friend. He was only a year or so old.
