This crate is an extra strong version of the Midwest ICrate.  Good for dogs that you are worried about trying to bend bars or chew wire.  Of course, if a truly psycho dog you need a solid body (like in a vet office) or a crate with steel tube instead of wire.

Weightstrength difference is most notable and has more value  in the bigger sizes.

In some sizes the Lifestages has slightly different dimensions than the ICrate.  Wire spacing can be a little tighter in some sizes too.which is a plus.
