I was starting to get nervous that just putting around the one wire in the first square wouldn't be secure enough, if it bent or they chewed through it, so now I'm trying to put them all through the second square.

Let's be clear. The doors are 18' wide. Not 16. 

I did.  Unless I counted wrong, but then I counted 18 inches and it worked fine. I must be losing it! We should also talk about utilizing mesh space. I was able to cover all the bottom FN with one roll (3 by 5) by zip tying the scrap together. In total it might take me 2 and a half rolls.

What?? You have to cover the bottoms too?

Oh...
I don't have enough to do it, and I don't think my dad will want to do it, so I can't. I'll just hope for the best. 

Seriously? I don't have any boys, and my girls aren't very naughty and aren't desperatley trying to get somewhere/escape. I'm not really worried. The cage is modded and put together, and my girls really like it.

Ack. I just got all the pices out of the box, bought the supplies and now I have no idea what to do, since no one will help me in my house xD

I did it by myself, I had HUGE wire cutters though, and little ones for touch ups. It's not that hard if you follow the instructions, make sure you have something heavy to held down the wire because it tends to bounce back and hit you in the face...  It's just tedious and if you have the right tools it goes by fast. Minus the breaks I took it probably took 3 hours.

I just bought my 2nd FN and decided to modify it prior to assembly. I have a feeling its a LOT easier to zip tie prior to putting the cage together than it would be to do all that zip tying after its all set up. Still, I had HOURS invested in this mod... But honestly, it wasn't difficult and I did not need my hubby's help until it came time to set up the 2nd level of the cage...

I ended up using 4 rolls of 2' x 5' wire but did not have enough to cover the top. I had very little waste, so I'm not sure how I only got the sides covered with 20' total length of wire 

I would make sure you have a GOOD pair of tin snips/wire cutters... that helps   And I had rolled out the wire the night prior to assembly and flattened it down with weights. That made measuring/cutting pretty pain free. I also made the error of zip tying the first panel with the little nubbies facing the inside of the cage.  Those little nubbies can be quite sharp, so I had to make sure I had the cut-part of the zip tie facing out so my girlies' little feet wouldn't get hurt

So far, the girls are loving the cage! The wire allows them to climb all over and provides me with a little peace of mind... Thanks again for your ideas on this mod!! It made my life a lot easier 

My fiance and I are considering getting a couple of FN's for the crew. I already know we will have to modify the girls cage of course. The boys we will have to test and see if we decide to get them a FN. Anyways, Most say they got the coated wire at home depot? how much was it? We haven't tried to look locally yet but there is a Ace hardware and a Home Depot near by. We also have a lowes, a bit farther. I was wondering if we can't find the mesh locally, has anyone found it reasonable online?? If so, could you please post a link. Thanks! 

My friend and I went to Home depot yesterday and could not find it. We went to the garden center and wondered around. We also looked in the regular fencing area but only found the galvanized. 

Anyone in FL found it? 

where did you get your ferret nation from and how much did it cost you?  I am looking into buying one and I am trying to find the best price.  It seems that online is the best, but I dont want to have to wait for it very long.  thanks!
