My cats love this carrier, even my 20 pounders.  They can see everything and it's sturdy. I personally love this design.  If they make a fuss just drop them in.  No more shoving and cohersing. More breathing room for them.  I have eleven rescue cats that get transported in this one at a time and it looks as good as new.  I don't think they will be destroying this anytime soon.  Made of durable hard plastic that cleans easily.  Recommend.

Pros: Sturdiness
Cons: Weight
