Just what I needed!

 from Mulberry, FL

I highly recommend this cage (I've gone through quite a few other types with my tree squirrels). The structure is solid, and easy to assemble - easy to clean. All of the shelves are removable and adjustable. The wire spacing is perfect for smaller rodents. Customization was a significant factor in my purchase decision. The cages are fairly large, and sturdy. The plastic covers over the wire shelving are fairly durable - if my tree squirrel (heavy gnawer) can't chew through it in a few mins, it's a good product! He chews on them, but hasn't made much progress in destroying them (over several weeks now) like he could with other plasticwood products in a matter of hours. He has plenty of room to climb and roam. I added this unit to the Ferret Nation Double cage (it actually fit it perfectly). The whole unit is HUGE! But I love it, and recommend Critter Nation to anyone with smaller rodents, wanting to give them maximum space to play and nest. (Ferret Nation cages have more vertical, wider spaced bars, but it's fine for my adult tree squirrel.) The doors aren't flimsy, and are hinged to open all the way so you have complete access to the entire cage! I put a small cat tree in this cage for my squirrel to climb and nest in... It's an all around great cage... And the price is incredible! I've had it for several weeks now, and I'm happy I chose this and the Ferret Nation cages. Midwest Homes has someone designing cages that knows small animals! I love it! So far, no other cages can come close - especially for the price!

Loves it!

 from tustin, CA– Verified Buyer

This make my two chinchillas happy! when my two chinchillas gotten big, i ordered it. they now are jumping around in huge cages! it was easy to assembly but it sometime doesnt fit so you will need to use hammer to make the circle metals smaller so that it will able to fit.

Solid Construction

 from Burlington, ON– Verified Buyer

This unit is very well made - I thought the last unit I bought was nice but there is no comparison to the Midwest.

Good cage add-on

 from Los Angeles, CA– Verified Buyer

Fast shipping, just what I expected. I got this as an add-on to my already 2-level Critter Nation cage. Now my chins have 3 levels and it makes a big difference with a lot more room to jump up and down ledges and shelves.

Liked it so much, I ordered another one

 from Georgia– Verified Buyer

The Critter Ferret Nation add on is great. I ordered one and just ended up ordering another one for my daughter because she liked mine so much. I had no problems getting it together.

Happy Ratties!

This cage is the safest and easiest to clean I have ever seen I plan to order another soon. I am completely confident that the service will be as prompt and perfect the second time too

Great addition to a great cage

 from Durham, NC

The add-on is nearly identical to the standalone single unit, except you get a second ramp and covering, and there's a small square hole cut in the floor panel. Assembly involves removing the roof of the single-unit and replacing it with the new floor panel, adding the sides, and putting the old roof on top of the new addition.

The second ramp gets animals from one unit to the other. There's a small hook attached to the new floor panel so that you can pull up the ramp and hook it to the floor/ceiling, effectively closing off the hole between the original unit and the add-on. Our hook was potentially mis-positioned, as it didn't seem to be in the right position to clip up the ramp, but we managed to make it work but putting a hook on the hook, which then could reach the ramp.

Assembly wasn't too difficult but was made much easier by having a second person handy. You'll also need a hammer (rubber mallet would probably make less racket) to secure the pieces.

Simply the best cage for rats

 from Montreal, QC– Verified Buyer

The new design for the small shelf is much easier to clean than the old 161's design, with the same type of mini scatterguard as the bottom pan that fits over the shelf architecture. Comes with ramp covers and a bottom pan with cut out.

Currently using it to house two separate male groups, hooking the connecting ramp up and using a full bottom pan works just great. Hooking it requires a bit of force, and looks like it bends the ramp a little to one side, but will probably not lose its shape.

The 163 arrived in much better shape than my 161 did. The packaging is still very simplistic, and the 'no tools' really still requires a hammer to bang wayward posts around/into slots but has still improved. Well worth the price and wait!

Because of its size and a few simultaneous steps, it's better if a second person helps hold things, but is possible to put together alone if you're patient/resourceful.

Critter Nation 163 Add On Unit

 from Towson, MD– Verified Buyer

Love this new addition! Got it very quickly and it was easy to assemble and connect to my existing cage, just as the rep on the phone told me. She even looked through the assembly directions for me, before purchasing, to see how difficult it was going to be. Would definitely recommend to others!
