Look, no offense, but you cited that you used it on six hamsters. One died, and the other had wettail SIX TIMES. That's because you didn't use correct antibiotics that got rid of the infection in the first place. The first hamster was probably not too far gone if he'd actually gotten to the vet and gotten correct antibiotics instead of over the counter junk.
Actually, I cited I had a hamster who had Wet Tail six times, not that I had six hamsters who had it.
And the reason he kept getting it, was not because I wasn't using the right "antibiotic", it was because I kept stressing him out. Like I said - most hamsters develop Wet Tail due to stressful situations, like cats who develop Urinary Tract Infections - it's not actually an infection, but it is an illness caused by a massive amount of stress that the animal is unable to handle. For my hamster who had 6 bouts of it, the illness first showed up when my parents drove him from New York to Michigan. A couple days later, he started showing signs of Wet Tail. I treated him, and it went away.
His second bout of it, was when I moved his cage to a different area in the house, and a 3 year old toddler started poking her fingers inside his cage. He got it again. I treated him, and he was fine.
Every time he got it, it was because I moved his cage to a different area in the house, or he was otherwise stressed. After I stopped moving his cage around, he stopped developing Wet Tail, and he lived to a healthy 3 years of age.
Dri Tail has never killed one of my hamsters - it's the actual disease, Wet Tail, who has, and that was only when I hadn't treated that hamster in quick enough time. My first experience with it, I caught it too late, and by then the illness had already done its damage. So I ask you - with the few hamsters I've had to actually develop it, when I administered the Dri-Tail within the first two days of the illness, how come it helped them, huh? How come, for any of the hamsters who preceded my hamster who had 6 bouts of it, when they developed Wet Tail, and when I administered the Dri-Tail, they never got it again? And lived long, happy lives after that? That wouldn't have happened, had the Dri-Tail not been right for them.
Perhaps it is "one of those things" ..but I doubt it. For all the years I've had hamsters, and for all the years I've treated those hamsters with Dri-Tail, I've never had a single casualty.
