i got a whippetxgrey good on lamp when ferreting verry obident, yet to catch me a hare and fox.
rag 2 foxes (we got denning) but he hasnt had the chance to get on above ground.
here in australia, you can probaly imagine the amount of flies we get in summer, i feed the ferrets at night and if they have left overs i take it out before it gets hot.
get your self some laxtose intolarant milk, and dilout the water only just a dash and they will think they are drinking milk. i do this in summer so ferrets keep up their fluid levels.
will get over weight alot easyer if you cut him, odnt know about drive. would be a shame to have a hunting dog with out drive.
hope it works out for you
