Hi barney benji here
my mummy told me off just because i was digging ok so it was by the side of my cage and if i would of carried on i would off escaped but digging is fun so why cant we do it.:?
basically everyone has said all you can say i would recomend a vet which you probably have been to already but oh well he is a cute bunny tho he can hear alright tho cant he?? hope its not a big problem it does look like a small hole
so sorry to hear that R.I.P but dont beat yourself up
such a cute little goose feel better you probably wont et over it for a long time but you will feel better someday
