I don't know about clay but our vet let us know that the place that cremated our Chelsea when she died would make a paw print in plaster of paris for us at a small cost. They put it in a nice double frame. You can buy plaster of paris at Michaels or other craft stores. It isn't hard to do, I have used it for children's handprints before.

I read about your loss. I hope you find out why you lost her.

Thank you. I called my vet (he's probably not open tomorrow) to see if he has anything, and will go to Michael's.

You can get air dry clay just about anywhere like Michael's or Walmart. That would do the trick. I believe there are also recipes online for making your own homemade clay.
