They make a stone for you to wear out of the ashes...so your beloved furbaby is always w/ you!
I (for certain reasons) have never been a fan of cremation...but didn't want to just bury Mojo somewhere (as I am sure we will move)....and the thought of ashes being in a little box....hmmm...I don't know...BUT this is wonderful! (IMO)
I don't know of anyone (personally) who has had it done though.
