I see absolutely nothing wrong with it, but I personally would keep the ashes separate. I believe that I would like to be able to tell everyone apart... you know? I can't say that for sure, though... as I only have one cremated pet. I suppose if you kept the ashes each in their own little bag in the urn then telling them apart wouldn't be as much of a problem.

I guess I think too much into it!

I am glad to hear of some other PTers who keep their pets' ashes. When people find out that we have Frisk's ashes they sometimes don't know what to think...
