Hello! I?m new here. I would like help administering ivermectin to my guinea pigs as they have been scratching and biting themselves quite a bit. I can?t afford to take them to the vet for another few months as I am between jobs. My first guinea Pig (Bear) weighs 950grams and my other (Tiger) weighs in at 785grams. I bought the aspen ivermax pour on for cattle. 250ml 5mg of ivermectin per ml. I?m terrible at math and wouldn?t want to overdose my little guys. I want to try this first if it doesn?t help I will have to use my emergency credit card to take them to the vet. Thank You. I have a 1cc syringe as well. All feedback is welcome!
