Usually the adults will take a bad URI much better than the kittens. The 2 cats of mine that wound up in an oxygen tent were only about 3 months old at the time, and were so congested that they were wheezing with every breath, and their eyes were so runny that they were nearly crusted shut. The vet put them under oxygen, gave them sub-q's and force fed them when they wouldn't eat. If Abbey gets to the point that her breathing is truly labored, you might want to consider doing this. She actually doesn't look at bad as my kittens were, but then a video doesn't always show what you see every day (and I'm sitting at work so can't turn the volume up).
Did the vet give you any antibiotics for Abby? If not, you might want to ask for some to give her as a preventative measure (opportunistic bacterial invasion).
And just fyi - Bogart (one of the kittens under oxygen), ended up with chronic, life long respiratory issues. His respiratory tract was damaged by the rhino and he sneezed and wheezed the rest of his life (lost him at 13 years to CRF). When it gets that bad, there can be permanent damage.
