Just wondering if anyone has suggestions/advice on how to trim guinea pig nails? Our guineas are held every day and are pretty calm, but as soon as I try to trim the nails, they get all wiggly. I am afraid I will hurt them if I try to trim while they squirm. Any techniques you know of, maybe a certain way to hold them or something? I'd hate to have to pay the vet to do this, but maybe that is what I will have to do. Thank you!
