I am not an animal fan, I have a cat though. A few years ago, I got a rabbit. The most cutest thing! I did the Paris Hilton thing and took it with me everywhere for a short time and it had it's own bag. I adored it.
In winter it would sleep in it's cage in the laundry and one morning my flat mate went in there naked at 7.30am to get ironing board. It was alive. When I went in an hour later it was dead. Poor thing saw him naked and had a heart attack.............. well that is what I reckon happened!
*I really do hope you get it back.. *
