I think she would limp, when my Henry took a giant leap and hurt himself, the emergency vet on the phone told me to hold a squeak toy near him and squeak it upwards, if he/she hops up for it fine, then they're ok. But if they don't want to or yelp, then you should prob. take them in.
I was a bit worried at this because, at first I thought...well if he did break it, why would I make him hop up for his toy? poor boy. But the vet said he would not make the effort if he was in pain etc.
Not sure if that helps
hope your furbaby is ok!
