Sometimes the Ivomec shots are not enough, especially if your fuzzies are
scratching other areas of teir bodies.  We run a shelter and recently got
3 ferrets in with the worst mite problems we have ever seen.  We have been
giving Ivomec shots every 7-10 days.  Check with your vet. sometimes these
little bugs can be persistent.  Feel free e-mail us at [log in to unmask]
