She got it at something called "pet supplies plus". It's a small chain here in NY I don't know where else they would be located. I also don't know if it is any good for the pigs. If anyone reading this thread has some thoughts on the matter I would appreciate it =]
Also, while my pigs did actually have a bad case if lice once, all piggies get itches. If they are constantly and violently itching, I'd say it would be worth checking out. But think of how many itches you get throughout the day. I would think piggies get just as many. I made the mistake of thinking they still had lice after the vet told me they had been cleared, all because I still saw them itching a bit. I paid $30 to go back to the vet and be told that they are just itching their normal everyday itches.
