I have a male silver that sucks on any other ferrets ear while they sleep. We had to remove him from his cagemate because he sucked on her ears so much that they bled. We now have him with one of the other males and he sucks on his ears also. We put bitter apple on the ears of the one being sucked but that only deters him for an hour or so. We have had the two silvers for almost a year. They were turned over to us after being dumped in a nearby park and left to fend for themselves. The sucking problem just started a month or so ago and we are at wits end as to why he is doing this. He is normal in all other aspects. He eats well, plays well and is a real lap ferret. Any suggestions out there in ferret land? Thanks. [Posted in FML issue 2738]
