There's a new trend in pet funerals. It's the BioUrn, a biodegradable cremation urn for pets. Put the ashes in the urn, plant it into the ground, water it, and you can have an actual tree grow as a permanent memorial to the departed. You can select the tree; and there are options, everything from sugar maples to oaks to flowering shrubs. Some people may find this sort of thing morbid, but I like the idea. It's all part of the cycle of life. There's also a human remains version available.
