Had my ferrets about a month now, they get handled at least twice a day and have stopped biting but are still intent on getting away from me as soon as they get picked up. Is the handling a persistance thing or will they always be rather frisky. Also they tip over their food bowl every day and won't touch their food once it's mixed in with shavings, any idea how to stop that, a special bowl or something? Cheers, Aaron.
