Well I keep 11 ferrets 4 of which are polecats they live in a hutch like enclosure about 5ft by 4ft 4ft high during the winter with a hinged door across the front, lots of different levels to play on. I cannot stress the need to keep them occupied. The bordom of these animals is very low, hence they are so mischivious ( probably spelt wrong ) but are greate pets. They like digging through soiled plants especially Mishca and Oscar. In the summer when my cars out and about they go into a garage which is like a barn conversion for them, i put in tunnels and hides in the middle and just have a seperating fence about 3ft high so they cant get out and they preffer this but only in the warm months. They will and do smell esspecially in the hounse, i keep then on wood shavings cleaned out daily which keeps the smell down ( get the rose scented type, it help no end ) but if you get the males snipped this helps the smell or have the scent glands removed if not god help you when they want to get it on with the ladies they reek !
