Wow! Those were almost exactly like my Honey's growths on his paw pads. He doesn't have the puffy big paw pad, but he does have those growth/horns. Some are very bent and look like claws, but the ones on his back feet (that he just let me look at before) look more like the ones that were coming straight out of the tops of the paw pads. My vet was telling me before that FIV+ kitties normally have bad teeth and feet. Not sure why or what the connection is, but most of the FIV guys I've had have all had very dry, almost dehydrated looking paw pads, and really bad teeth. This poor guy has 4 teeth left. The top and bottom fangs.
