a very very verylong time ago i took in a cat who had a dislocated hip. the vet tried to re-locate it but it woudl not stay. we kept her confined for a few weeks so any soft tissues coudl heal adn after that she did just fine.
Within the past year I took n a cat wth a badly broken pelvis. She was kept on crate rest for six weeks, it has healed and she gets around fine. her main limp is caused by her busted Achilles tendon, her hips are ok.
for a person a dislocated hp is extremely painful, but our hips are very different since we are bipedal. a hip injury for us throws off not just out hip but out entire stance, so it affects our spine, everythng. Quadrapeds can cope with hip inujuries much more successfully.
If this were my cat, i would keep her confned in a large crate for a couple weeks to see how she does, just n case. This would let everything heal up, give time for any swelling to go down. If she is in pain she won't want to be very active, or she will avoid using that leg. If you see her using the leg and being active, she is ok. Pat her and stroke over the hip, see how she responds. If she yells or jerks away or swats you then you know it's sore.
Glad you found us
