I bury in the yard, then plant a bush or perennial over the grave. Inevitably I refer to the plant by the pets name...so I have living memories of a sort.Have you ever seen the bio degradable cup with a seed you can get and basically your ashes provide nutrients to grow a tree on your choosing. I like that idea. I suppose you could do the same with animals too... I actually may do that with most pets since I forget i'd even read that. Burying is fine, in fact I want to end up in the ground and think my animals eventually should too, but the idea of rotting there is just yucky.
