To Cynthia Mosch: >Also, I have some heartworm medication that was prescribed for a previous >ferret & am wondering how long the stuff keeps (Ivomec:propylene glycol)... >The other option is interceptor (milbemycin oxime) tablets which are 2.3 >mg each. Is one tab. the right dose for a ferret of approx. 1 lb.? Cindy - the ivermectin/propylene glycol is good for about a year provided it does not get exposed to sunlight - the bottle shoudl either be a brown bottle (as most are these days, or wrapped in foil. I'm not familiar with the dosages for interceptor - so you might call the vet who filled that prescription for you... Bruce Williams Bruce H.
