You don't have to shave them. The sequential treatment will take care of the lice and the nits.
This is what my vet recommended, because she said that just to be absolutely sure that we get all of the nits, this would be best. I respect and appreciate your opinion very much, and I am very grateful for all of your advice, but as this is what my vet recommended (who knows a lot about guinea pigs and is quite cavy savvy in her medical experience) I will be going with her instincts as she has seen and examined my pigs.
Please understand that I do not mean to offend you in any way, and don't take it personally. I trust my vet, and she is very good with pigs. I just figure I'd go with her gut and vet training on this one.
Toni has a definite case of lice, which she picked up at her rescue. She also has a possible URI, though it isn't severe. The vet said that her left lung sounded fine, but her right lung was a little heavy. Because Toni also had some little crusty patches around her nose and eyes, the vet suggested meds. She is on an oral antibiotic twice a day for 2 weeks to treat the URI, and they are both on topical Revolution, though the vet is administering that. On Monday, Toni will have to be shaved, but Griffin will be spared the embarassment as our vet found no adult lice on his body. They will both, however, be treated with Revolution which the vet gave them a prescription for.
Because of the lice, all of the fabric that they have come in contact with must be put in large plastic bags and kept in a warm place for a week, with no oxygen. Then, I will wash them really well and we can use them again.
Because it would be so expensive and time consuming to buy 3 or 4 new sets of fleece and towels for the next 2 weeks, the vet recommended that we lay newspaper down on the bottom of the cage and put a little bit of CareFRESH on top of that.
In 2 weeks, Toni and Griffin will go back to the vet to get their second topical treatment of Revolution, and that will (hopefully) kill off the last of the lice. Thank gosh this crappy day is nearly over.
Thank you all for your patience and advice. I really appreciate everything, and I will have some 'pigtures' up soon of Toni's new 'do!
