It sounds like Petco will be carrying Real Canadian Ferrets. They mark their ferts with the blue vertical bar. I have two from them and they are the first ones I look for when getting a fert. As has been discussed before, they are a little toothier which I like, but they are just as easy to train as any other. One thing to watch for and I'm not sure if this is a problem with other ferrets from other breeders or if it is just the RC ferts, is that of the four RC ferrets I've owned, two of them have had allergies to mold. It only shows up when it rains for any length of time, especially in the fall. Compared to my two MFs, the RCs are more full of it!! Is the RC breeders any different from MF? Probably not, but the babies we get here are bigger than the MF babies. Not sure if they wait longer before shipping or not, but problems will still exist. So check out the kits thoroughly before purchasing. Dooks and chuckles from Cindy and the gang at Hiland Ferrets [Posted in FML 6027]
