I've posted some 3D sculpts of the molds and such the past few days, have a comparison picture now!

The top image is the heart paw mold cast in medical grade red pigmented silicone with a fleece fabric backing.

the bottom image is the 4 finger hand paw fingerpad mold cast in medical grade white pigmented silicone with a fleece fabric backing.

These are for  WolfElysia's fursuit which I should be getting photos of in the next day or so, these pads were cast and pulled a few days ago.
