Hi All - In reference to collars I use the safety nylon for the big males (Deno is close to 4 pounds and so is Gizzie) when we go out but don't keep anything on them at home. Both Deno and Gizzie keep the collars on and even fuss at me when I take them off - I think they'd be happy to wear them all the time :-), but I know they'd stash them somewhere when they come off. I use H halters for the girls for our walks and it is difficult to find them small enough for some. Treats - I guess you could call their morning dry cereal (honey nut cheerios) a treat. Other than that they don't care for other human food, except for my milk. Every time I eat a bowl of cereal there's at least one little furry head hogging the bowl! Well after 3 free years, I've got them - fleas! After taking the ferrets and dogs for walks several times I noticed a couple. We must have picked up some hitchhikers along the way. Anyway instead of spraying or powdering the ferrets I spray a small amount on the counter and I search through their fur. Each time I find one I dip my finger in the spray and put it directly on the flea. Works great! After I've gotten all off I spray my hands and rub a little into the fur. The ferrets don't mind terribly, and some even enjoy the additional handling. Hugs to all! tle [Posted in FML issue 0952]
