My tort needs to take Fenbendazole for worms. This is the second treatment he has had. Seems like the first time did not work. My tort is 30 grams and needs 0.02CC of it. I am not sure he is getting it all,if any? I cut up zucchini, use mazuri both of which he likes,but seems like he is not eating it all. Seems like I am just wasting the meds, with each food I try. The vet does not give much to waste. Any good idea ?
