User-configurable Pedigree
This picture contains two scripts. The free KittyCatS Pedigree script, and my take on a customer-configurable script. You can copy both scripts to make your own Pedigree givers.
To use my script, however, you need to put the KittyCatS script in prim 2 of a linked object. My script can go in any other prim; but probably should go in the root. In this way, when your customer clicks on prim 2, they get the pop-up link to the cat's Pedigree page and when they click anywhere else on the object, they'll get a dialog asking for a cat UUID (which you must own).
