I found a carpenter bee hole in the wood under one of my rabbit cages about 3 weeks ago and I filled the holes and they drilled through that, so then I covered it with a some metal and tape ! I found one of my rabbits dead a week ago and it was her cage the hole was under ! When we were getting her out of the cage to bury her I noticed that the tape had came down and a bumble bee flew out !! Someone told me that the female bee's are the only one's that sting and that they can sting up to 8 times if felt threatened ! I don't know how true that might be ?? Do you think it could of killed her ? I feed all my rabbit's the same thing and they have fresh water everyday ! She was only 4 1/2 years old and I have other rabbits older than her !! :'( I found her one week ago today ! :''( R.I.P. HUNNY BUN
