Alright so my two boys apparently have lice, I can see the little worm like bodies on them. I can also see some of the nits (eggs) on Lightning. Now Gorgeous Guinea makes a shampoo called Lice n' Easy it is specifically for lice on guinea pigs. I know most people say no shampoo for parasites on guinea pigs, so would it be safe to treat with the Lice N' Easy? I also already have the pour on Ivermectin on hand, but the gorgeous guinea site actually saids it's not needed since lice aren't blood suckers. What do you all think?
