The name on the box is FerreTrail FUN-NEL maze. The address I find on the
box is: Pets International Ltd, 2605 S Clearbrook Dr, Arlington Heights, IL
60005. I found the phone number in a business directory: 708-956-1130 . You
can get straight ones or angled ones and six holed balls to connect tubes
going in different directions (I have not seen one holed balls). The box has
got pictures of ferrets all over it, but also says good for hedgehogs,
rabbits, etc. The box says to send a picture of your ferrets playing in your
most creative FerreTrail and they will send you a free ferret gift.
 
I can't help thinking that maybe those one holed death balls that people say
can cause suffocation or overheating or whatever might have been part of the
FerreTrail and were supposed to end a tube so that fat ferrets could turn
around without having to back out of the maze (this is conjecture I have no
idea if this is true but it seems very possible). If they were used in this
capacity I can't see how suffocation/overheating could occur as the attached
tubes are vented for air flow. The 6 holed balls are part of the FerreTrail
and are supposed to be used as connectors although I have seen people use
them alone too. I have seen ferrets sleeping in them with their heads
hanging out of the holes in pet stores. The 6 holed balls that I have, I use
for connectors, as I feel the edges around the holes are too sharp to rest a
neck on.   Charlene
