Awwww, Roo....
I'm so, so sorry.
Although getting a new pet does help with the loss, it never really replaces completely. Poor bunz.
I have to ask, though....why in God's name would your neighbor want to kill your pets....especially a penned lil fluff, such as your harmless bunny?
Huggs to you.
Talk to you soon, my Roo~
