- My home, ruled by pigs!
I´m not very cavy knowledgeable, so you may want to wait for another reply from some who is.
I think it is a spur, my three (brothers) have them also. The vet told me to trim them, and put "H-Cream" on (for piles in humans). It seems to help, but they are still coming back. I just keep trimming them back when I trim the nails, it doesn´t bother them, so I´ve not taken further action. I wonder if it´s genetic? None of my other pigs have had it, and none of my friends pigs either. Anyone have any ideas on this?
