Ernie,
Yep checked out your web-site & calls/sounds. They are very good, especially the "Red Fox" /ubbthreads/images/graemlins/grinning-smiley-003.gif. We had 2-Red Fox cubs, when my Bro's & I were younger. We keep'em in a large rabbit pen, in the back yard. They'll also make a very loud & raspy "Kacking/bark" noise. Those two pups, would cut loose right @ darkness(every-night /ubbthreads/images/graemlins/mad.gif). They'd also yap & wail, like a coyote.
Drove our Mother & the neighbors crazy /ubbthreads/images/graemlins/grin.gif(we lived right in the middle of town, then LOL!). Finally had to get rid of 'em. They were both litter mates(male & female), that our Dad brought us, one spring. I think he was trying to push our Ma over the edge! /ubbthreads/images/graemlins/smiliesmack.gif
