Should a person bury their loved one in their back yard?

I know about your recent loss, and I am sorry. If you have had your cat cremated, then you may keep his urn or box where ever you wish. After cremation, it is legal to bury the box of ashes in your back yard, and they have some very nice stones you can purchase from pet catalogs for that purpose. I don't have a back yard, since I live in an apartment, and I keep the little box hidden on the top of my china cabinet.
