I'm like some of the others in regards to the two: I don't think attention span has anything to do with memory in ferrets. Mine have the attention span of about 1/100th of a millisecond. But memory? That's different all together. For about two years we had our boat in slip E-7. When returning from walks all of the kids automatically turned onto our finger pier beside the boat. About 8 months ago we moved out to slip E-43. Well, now when we return from walks they all STILL want to turn in at E-7. With a little coaxing they will finally move on to our current slip. Some of them will even bound up the steps and jump over onto the boat. (PS: When they jump I ALWAYS have them securely leashed so they don't make a splashdown!!) [Posted in FML issue 3850]
