This is the single nugget of information that would influence most pet owners choice of cremation service provider.
People I speak to are horrified to learn that Vets routinely freeze deceased pets while they await collection. This is done out of necessity, since most practices only have one collection per week. The freezer will contain all the pets whether they are to be mass cremated or given an “Individual” cremation. Ask your Veterinarian if this is a policy they follow.
