My cats are normally indoor/outdoor cats but with Dino having the buster collar on at the moment, every other word I seem to say is shut the door and don't let the cat out, so I feel your pain!
Glad to hear you got her back home and hope the stiffness in her legs is starting to ease.
This thread has made me realise that I don't actually know what happens out of hours with my vet. I used to live in Burgess Hill, Sussex, and they were very good there. There were several practices and they had a good emergency system.
I'll have to speak to my vet about this and found out what we do here. Touch wood just never need to use it.
