Funeral homes aren’t just for dead peopled . They’re for our passed–on pets too these days. Pet Angel Memorial Center in Carmel. Indiana, helps guide grieving (悲痛的)animal owners through a vast range of burial and menorial options . The staff of five, all former clients (顾客), then carries out the owner’s wishes . Perhaps the most important service the center provides, though, is an understanding to cry on .

Owner Coleen Ellis started the country’s first pet funeral home there years ago after the death of her dog Mico. It was then that she discovered her veterinarian(兽医), like most throughout the United States, put dead animals in garbage bags and stored them in a freezer for up to one week . A disposal company then picked up the bodies and took them to a landfill(废物埋填地)site.

Before opening Pet Anget Memorial Center, Ellis worked in human funeral homes for 15 years, helping guide families through the end of life process. Her work with pets, though, is unusual. Only a handful of animal funeral homes exist, most of which Ellis said she helped get started.

Honoring dead pets and honoring people are similar in many ways. The 1,200 square –foot memorial center, located outside of Indianapolis, offer a full line of memorial items . The lowest priced package starts at $ 230  and includes pick-up , as well as a keepsake(纪念品)paw print. Friends, family and surviving pets often accompany grieving owners.

The atmosphere is different from a human funeral home, where people stay their distance to give the grieving family privacy. At the center , pet owners mourn together . Often times , if two visitations are going on, the families will share stores about their dead loved ones. It’s a very good healing experience.
