hi val, i never use squeeky toys as ferret toys , i had a major problem with a rescue jill she was in a run with another couple of rescues waiting to be re homed, my lot were in there run as normal & played quite happily with there tubes & other toys, but a couple of the toys had squeekers in them the poley jill in the other run changed in an instant the second she heard the noice, running around & being very aggresive lunging at the run mesh, but most scarey was the change towards the other ferrrets attacking them grabing them around the front of there necks, this went on for around 10 mins. i had to remove all the toys from the other run & allow her to calm down before i could get anywhere near the 2 shocked ferrets she had attacked, it was a horrible experience i spoke to a gamekeeper friend who said rabbits squeel underground & this noice may have been enough to awaken the killer in her but even so all wasnt lost i managed to re home her to a friend & she still has her kay [Posted in FML issue 4377]
